Hi Yves,

Sorry, of course this is the "potential" syntax.

Done

I added "(including attributes and textual content of child elements)"
to make clear that we use the semantics of xml:lang. If the mapped
markup is an element, it would not make much sense, since its value is
the xml:lang value.

good point, I still have to add that.

What do you all think about locale rule? Also, Richard had some concerns
about the terminology "map", "select". Richard, is this now fine with you?

Below the new version.


default namespace = "http://www.w3.org/2005/11/its"

start = itsGlobal | itsLocal

itsGlobal = element documentRules { ns*, documentRule+ }

ns = element ns { attribute prefix { xsd:NCName }, attribute uri {
xsd:anyURI } }

selector = attribute selector { text }

documentRule = translateRule | locInfoRule | dirRule | termRule |
langRule | localeRule | rubyRule | withinTextRule

translateRule = element translateRule { selector, attribute translate {
"yes" | "no" } }

#About locInfoRule: At the locInfoRule element, there must be either a a
locInfo element [not attribute] or a locInfoRef attribute. If neither is
present, there must be either a locInfoMap attribute or a locInfoRefMap
attribute. There is an optional locInfoType attribute.

locInfoRule = element locInfoRule { selector, attribute locInfoRef {
xsd:anyURI }?, attribute locInfoRefMap { text }?, attribute locInfoMap {
text }?, attribute locInfoType { "alert" | "description" }?, element
locInfo { text }? }

dirRule = element dirRule { selector, attribute dir { "ltr" | "rtl" |
"lro" | "rlo" } }

#About termRule: In an instance document, we would need an attribute
term="yes" to indicate a term. In the global rule, "being" a term is
expressed via the name of the element termRule, hence the attribute
term="yes" is not necessary any more. The attributes termRef and
termRefMap are alternatives. It is an error if they occur at the same
termRule element.

termRule = element termRule { selector, attribute termRef { xsd:anyURI
}?, attribute termRefMap { text } }

#About langRule: The element langRule is used to express that a given
piece of content (selected by the attribute langMap) is used to express
language information as defined by RFC 3066 or its successor. Example:
<its:langRule its:selector="//p" its:langMap="@mylangattribute"/>
expresses that all p elements (including attributes and textual content
of child elements) have a language value conformant to RFC 3066 or its
successor. The value is given by the @mylangattribute attached to the p
elements.
langRule = element langRule { selector, attribute langMap { text } }

#About localeRule: The element localeRule is used to express that a
given piece of content (selected by the attribute localeMap) is used to
express locale information. Example: <its:localeRule its:selector="//p"
its:langMap="@mylocaleattribute"/> expresses that all p elements have a
locale value given by the @mylangattribute, which is attached to the p
elements. The value of @mylocaleattribute might be compliant to RFC 3066
bis, but this is not mandatory.
localeRule = element localeRule { selector, attribute localeMap { text } }

#About rubyRule: The element rubyRule is used (1) to map existing ruby
markup to ITS ruby, which itself is defind in terms of the W3C ruby
specification, or (2) to add ruby text to attribute values. Example for
(1): <its:rubyRule its:selector="//span[class='ruby']"
its:rubyBaseMap="span[class='rubyBase']"
its:rubyTextMap="span[class='rubyText']"/> . Example for (2):
<its:rubyRule its:selector="/body/img[1]/@alt" its:rubyBaseMap="."
its:rubyText="World Wide Web Consortium"/> . It is an error if both an
its:rubyText attribute and an its:rubyTextMap attribute occur at the
same <its:rubyRule> element.
rubyRule = element rubyRule { selector, attribute rubyMap { text }?,
attribute rubyBaseMap { text }?, attribute rubyTextMap { text }?,
attribute rubyText { text }? }

#About withinTextRule: withinTextRule is based on Yves / AZ proposal,
see http://www.w3.org/Bugs/Public/show_bug.cgi?id=2878
withinTextRule = element withinTextRule { selector }

#locale usage of ITS are itsLocalAttributes, or ruby. Just for
convinience, the span element contains the itsLocalAttributes.
itsLocal = element span { itsLocalAttributes, text } | rubyLocal

itsLocalAttributes = translateLocal | locInfoLocal | dirLocal | termLocal
translateLocal = attribute translate { "yes" | "no" }?

#About locInfoLocal: There must be either a a locInfo attribute or a
locInfoRef attribute. There is an optional locInfoType attribute.
locInfoLocal =  attribute locInfo { text }?, attribute locInfoRef {
xsd:anyURI }?, attribute locInfoType { "alert" | "description" }

dirLocal = attribute dir { "ltr" | "rtl" | "lro" | "rlo" }?

#About termLocal: the attribute term is mandatory, the attribute termRef
is optional.
termLocal =  attribute term { "yes" }?, attribute termRef { xsd:anyURI }?

#On ruby: todo: still need to write the ruby content model, which is
identical to w3c ruby, and global ruby rules.
