I agree. I just don’t know yet what to conclude with regards to the rules file. If we keep it simple like it is currently, see below:
<its:rules xmlns:its="http://www.w3.org/2005/11/its" version="2.0"
xmlns:xlf2="urn:oasis:names:tc:xliff:document:2.0" queryLanguage="xpath" xmlns:itsm="urn:oasis:names:tc:xliff:itsm:2.1">
<its:textAnalysisRule selector="//xlf2:mrk[@type='itsm:generic' and (@itsm:taClassRef or @itsm:taIdentRef)]" taClassRefPointer="@itsm:taClassRef" taIdentRefPointer="@itsm:taIdentRef"/>
<its:textAnalysisRule selector="//xlf2:sm[@type='itsm:generic' and (@itsm:taClassRef or @itsm:taIdentRef)]" taClassRefPointer="@itsm:taClassRef" taIdentRefPointer="@itsm:taIdentRef"/>
</its:rules>
it needs the additional machinery discussed in this thread. If we make it more complex (the XPath 2.0) stuff, it will fulfill the
"A nice ready-to-use reference that an ITS-only processor can use out of the box (as long as it supports XPath 2)“
requirement but only for ITS processors that support XPath 2.0. Not sure how to move forward.
Best,
Felix

>> Actually, as long as ITS module in XLIFF is just a set of annotation attributes that follows general XLIFF annotation rules, and has nothing to do with the approach of the ITS for general XML, excepts for the meaning of the data categories, it is ok with me. Yet deviating from that line, it complicates the matter. It is not clear, why there should be any specific ITS external rules, selectors and so on. For example, splitting/combining segments is quite a usual user option in the translations systems. In case of XLIFF, it leads to the changes in the underlying XML structure. Suppose there is a selector that becomes invalid due to such changes. The requirement of keeping the selectors valid would have made the general operation of splitting/combining segments dependent on the knowledge of the specifics of an optional module, which I believe is not particularly good.

> Interesting - so you are basically saying that one should not process XLIFF that contains ITS markup with an ITS processor. The idea of the rules was to make such processing possible for an ITS processor. But maybe the feedback is that this should not be tried and that we should only push for ITS processing by XLIFF processors (which know how to deal with annotations etc. anyway)?
