RE: 1.1 spec correction for unspecified submission method

What do we tell processors to do in this situation:
 
<xf:model>
  <xf:fnord />
</xf:model >
 
?

That *is* what we say now, in prose.  The problem is that we then don't
say what happens when the requirement is not met.  It's a requirement on
authors not on implementers, so we either have to tell implementers what
to do when authors don't meet the requirement or the implementations
will not all behave the same authors don't meet the requirement.

Ah, I checked the 1.0 schema; of course.  In Relax NG you can specify
that one or the other must be required. 
I hear a later revision of XML Schemas allows co-occurrence constraints
as well. Why not just say it in prose then? 
4) A conforming document must have either a method attribute or a method
element.

Hi Leigh, 

The problem is that we already say, from the schema perspective, that
the method attribute is optional.  This is because we also have a method
element child of submission, which can computationally determine the
method with the value attribute. 
Further, because the method attribute exists, the method element child
is not required either, again from the schema perspective. 

So we have this situation where neither the attribute nor the element is
required, but we claim that one is required, but we don't say what
happens if you don't put one.  The options are 

1) Make method="get" the default if neither the attribute nor the
element is given. 
2) Specify xforms-submit-error (which we did for the resource
attribute/element pair; see the diff on step 7 of submit event
processing) 
3) Continue to not say anything and let implementations pick their own
way of handling the problem (some will do #1, others #2, and others ...)

Or leave unspecified behavior and let the user agent handle it however
else it handles Schema violations. 
 
<xsd:attribute name="method" use="required">

Hi Erik, 

Another more compelling possibility is to simply say that "get" is the
default method.  This is simpler editorially, does not introduce a
further error-type, and aligns with the default currently used on the
web.  Does that sound good?

That sounds reasonable except that it is a little annoying to have to  
add a new "method-error" error type, since this type does not exist yet.
