RE: [xliff-comment] Including XHTML with XLIFF

[Doug <doug@ektron.com>]

So far, I have not needed to use XHTML tags in inline XLIFF tags (e.g., PH),
but I need them in the <source> and <target> tags. I noticed the XLIFF
schema already has multiple locations for elements/attributes of other
namespaces.

For validation, I added the <xsd:any> element to the XLIFF TextContent type
as shown below.

	<xsd:group name="ElemGroup_TextContent">
		<xsd:choice minOccurs="0" maxOccurs="unbounded">
			<xsd:element name="g" type="xlf:ElemType_g"/>
			<xsd:element name="bpt" type="xlf:ElemType_bpt"/>
			<xsd:element name="ept" type="xlf:ElemType_ept"/>
			<xsd:element name="ph" type="xlf:ElemType_ph"/>
			<xsd:element name="it" type="xlf:ElemType_it"/>
			<xsd:element name="mrk" type="xlf:ElemType_mrk"/>
			<xsd:element name="x" type="xlf:ElemType_x"/>
			<xsd:element name="bx" type="xlf:ElemType_bx"/>
			<xsd:element name="ex" type="xlf:ElemType_ex"/>
			<xsd:any namespace="##other" processContents="strict" minOccurs="0"/>
		</xsd:choice>
	</xsd:group>

The XLIFF XML Schema is from message "Formal Extensibility" posted 06 Sep
2002 by Yves Savourel.

In addition, I did finally find the way to suppress the namespace attributes
from the output. Use the exclude-result-prefixes attribute.

For example,

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xlf="urn:oasis:names:tc:xliff:document:1.1" xmlns=""
exclude-result-prefixes="xlf">

I don't think it should validate. Trying with XMLSpy 4.4 and the latest
XLIFF XSD it doesn't. The reason is that there is no extension point in any
of the inline elements (<ph> in this case). In order to have non-XLIFF
elements in <ph> you would have to have an <xsd:any namespace="##other">
element in the definition of <ph> and there is none.

We had (and I guess still having) this discussion regarding non-XLIFF
namespaces in inline elements with Martin Dürst at the Unicode conference in
Dublin. Currently (1.0 and the latest draft of 1.1) they are not allowed. I
recall sending a list of reason and examples, but I can't find it anymore.
The reason is basically that XLIFF is meant to be generic, not specific to
XML content (many content of XLF file are coming from non-XML douments), and
treating XML content differently leads to make exception cases. I don't
think we have close the discussion on this though.

Comments anyone?
