Abstract
--------
# This specification defines Web Forms 2.0, an extension to the forms features
# found in HTML 4.01's forms chapter. Web Forms 2.0 applies to both HTML and
# XHTML user agents, and provides new strongly-typed input fields, new
# attributes for defining constraints, a repeating model for declarative
# repeating of form sections, new DOM interfaces, new DOM events for validation
# and dependency tracking, and XML submission and initialization of forms. This
# specification also standardises and codifies existing practice in areas that
# have not been previously documented.
#
# HTML4, XHTML1.1 and the DOM are thus extended in a manner which has a clear
# migration path from existing HTML forms, leveraging the knowledge authors
# have built up with their experience with HTML so far.

1.3 Relationship to XForms

1.5 Missing Features

1.6 Conformance Requirements
----------------------------
# All other content in this specification is intended to be normative.
All other content in this specification is <> normative.
# Compliant UAs must implement all the semantics of those specifications
# to claim compliance to this one.

1.7 Terminology
---------------
# Generally, when the specification states that a feature applies to HTML or
# XHTML, it also includes the other. When a feature specifically only applies
# to one of the two languages, it is called out explicitly, as in:
Generally, when the specification states that a feature applies to HTML>, it
also includes XHTML and vice versa<. When a feature specifically only applies
to one of the two languages, it is called out explicitly, as in:
# ...it is possible that authors would prefer to declare the page's forms in
# advance, in the head element of XHTML documents (this does not apply to HTML
# documents).
This example makes no sense in this context. Find another one.
2. Extensions to form control elements
--------------------------------------
# Also, as controls no longer need to be contained within their form element to
# be associated with it, it is possible that authors would prefer to declare
# the page's forms in advance, in the head element of XHTML documents (this
# does not apply to HTML documents). This is therefore allowed, although only
# when the form element is empty.
Also, as controls no longer need to be contained >by< form element to be
associated with it, it is possible <> to declare the page's forms in
advance<>. >The <form> element is therefore allowed in the <head> element of
XHTML documents<, although only when the form element is empty. >(This does
not apply to HTML.)<
# Forms are not related to ancestor forms in any way semantically,
Forms are not >semantically< related to ancestor forms in any way<>,
2.1 Extensions to the input element
-----------------------------------
# UAs must not submit numbers in invalid formats (whatever the user might
# enter).
Delete this. It's covered by the type-checking requirements, same as with
all the other types.
# Although if they are required fields, they will stop submission
Although if they are required fields, they will >block< submission
2.1.1 Ranges
------------
> To limit the range of values allowed by the above types, two new attributes
> are introduced, which apply to the date-related, time-related, numeric, and
> file upload types:
...
> For date, time and numeric fields, the values indicate the allowed range. For
> file upload fields, the values indicate the allowed number of files.
To limit the range of values allowed by the above types, two new attributes
are introduced<>:
...
For date, time and numeric fields, the values indicate the allowed range. For
file upload fields, the values indicate the allowed number of files. >For all
other types, the attributes must be ignored.<
2.1.2 Precision
---------------
# This specifies how many digits may come after the decimal point when the
# number is serialised with a zero exponent, ignoring trailing zeros. Zero
# itself is always valid (assuming it is within the range of min and max of
# course).
This specifies >the maximum number of digits that< may come after the decimal
point when the number is serialized with a zero exponent, ignoring trailing
zeros. <>
# This specifies how many digits may come after the decimal point when the
# number is serialised with an exponent such that
This specifies >the maximum number of digits that< may come after the decimal
point when the number is serialised with an exponent such that
# If a UA needs to round a number to its nearest binary equivalent, for example
# when converting a user-supplied decimal
If a UA needs to round a number to its nearest binary equivalent, >as, <for
example>,< when converting a user-supplied decimal
2.2 The output element
----------------------
# The output element acts very much like a span element, except that
# it is considered to be a form control
The output element acts very much like a span element<> except that
it is considered to be a form control
# It has no attributes beyond the common attributes
^^^^^^^^^^^^^^^^^
Link to http://www.w3.org/TR/html40/sgml/dtd.html#attrs
# This is similar to the way textarea elements work, except that the
# contents of an element for output controls reflects the current value
# not the initial, or default, value.
This is similar to the way textarea elements work, except that the
contents of an >output element< reflects the current value>,< not the
initial<> value >(defaultValue)<.
# Its value can be set dynamically via the value DOM attribute,
# thus replacing the contents of the element.
Its value can be set dynamically via the value DOM attribute,
>whose value then replaces< the contents of the element.
2.3 Extensions to the select element
------------------------------------
# Previous versions of Web Forms were inconsistent about whether the initial
# option element of a single-select select
Previous versions of Web Forms were inconsistent about whether the >first<
option element of a single-select select
# If the field doesn't match any of the other values, it should be treated as
# this value.
Delete. This is covered by the prose right after the value definitions.
# If the precision attribute's value does not match any of the allowed values
# given above, for example 0e, +1, or -2dp, then the value integer must be
# assumed.
If the precision attribute's value does not match any of the allowed values
given above, <> then the value integer must be assumed. For example 0e, +1,
and -2dp are all treated as integer.
# User agents implementing this specification must select the initial option
# element of a single-select select element with no otherwise-selected items.
If no other options are selected, user agents implementing this spec must
select the first option element of a single-select element.

2.7 Extensions to the submit buttons
------------------------------------
# 2.7 Extensions to the submit buttons
2.7 Extensions to <> submit buttons
# For this reason, the following attributes are allowed on submit buttons:
# action, method, enctype, replace, and target. **When not specified, their
# values default to the values given by their form element.**
#
# If a submit button is activated, then the submission uses the values as given
# by the button that caused the activation, **with missing attributes having
# their values taken from the form.**
Highlighted phrases should be reduced to just one. (Also, the remaining phrase
should be clear as to whether getting the attribute value from the DOM would do
a lookup on the form element or not.)
2.8 Extensions to existing attributes
-------------------------------------
# When applied to a fieldset element it overrides the disabled attributes of
# any descendent form controls
When applied to a fieldset element it >disables all< descendent form controls
2.9 The pattern attribute
-------------------------
# In the case of the email, tel, and uri, the pattern attribute specifies
In the case of the email, tel, and uri >types<, the pattern attribute
specifies
# When the value doesn't match the field's type, a ERROR_TYPE_MISMATCH error
# occurs; when the value doesn't match the pattern, a ERROR_PATTERN_MISMATCH
# error occurs.
When the value doesn't match the field's type, >an< ERROR_TYPE_MISMATCH error
occurs; when the value doesn't match the pattern, >an< ERROR_PATTERN_MISMATCH
error occurs.
# Additional information could also be included, so long as it assists the user
# in entering the field. Otherwise, assistive technology would be impaired.
Additional information could also be included, >so< long as it assists the
user in entering the field. Otherwise<> assistive technology would be
impaired.
# For instance, if the title attribute contained the caption of the control,
# assistive technology could end up saying something like The text you have
# entered does not match the required pattern. Birthday which is not useful.
Insert an em dash before "which is not useful", and please make the <samp>
display: block.
2.11 The form attribute
-----------------------
# Setting an element's form attribute either to a non-existent ID, to the empty
# string, or to an ID that identifies an element that is not an HTML form
# element, disassociates the form control from its form, leaving it unassociated
# with any form.
Setting an element's form attribute either to >an ID that does not identify an
HTML form element or to the empty string< disassociates the form control from
its form, leaving it unassociated with any form.
# unless they have form attributes of their own, or are contained inside forms
unless they have form attributes of their own<> or are contained inside forms
# When forms are submitted, reset, or have their form controls enumerated
When forms are submitted, >are< reset, or have their form controls enumerated
2.12 -> 2.15
------------
No editorial comments (yet).
2.16 Handling unexpected elements and values
--------------------------------------------
# The value of the control, if not specified explicitly, is initialized using
I suspect that you can be a bit more precise than saying "the value of the
control". I'm not sure though. It just kinda stood out...
