Warnings in Jenkins based on TEI_to_odd4odds.xslt

[jamescummings]

When Jenkins builds TEI-dev it gives a couple of warnings:

isoschematron:
     [echo] XSLT generate ISO schematron tei_customization.isosch from compiled ODD 
     [xslt] Processing /var/lib/jenkins/jobs/TEIP5-dev/workspace/P5/Exemplars/tei_customization.odd.processed to /var/lib/jenkins/jobs/TEIP5-dev/workspace/P5/Exemplars/tei_customization.isosch

     [xslt] /var/lib/jenkins/jobs/TEIP5-dev/workspace/P5/Exemplars/tei_customization.xsl:1470:1: Warning! The child axis starting at an attribute node will never select anything

Which, if I've followed them back correctly, refer to the schematron rule surrounding @xml:id needing to be unique in the document for the tei_customization ODD. This is generated by https://github.com/TEIC/TEI/blob/dev/P5/Utilities/TEI_to_odd4odds.xslt#L1397 and it is complaining because of its lack of specific context.

Is there: a) A way to fix this so the schematron doesn't complain? b) A way for Jenkins to be told to ignore it? c) A real need for this? Doesn't any normal xml schema validation also do xml:id uniqueness testing?

[martindholmes]

Jenkins can be told to ignore it, but that should only happen if we're sure it's the right thing to do.

[jamescummings]

I'm not sure it is, hence assigning @sydb since I think the XSLT producing this schematron is his.

[ebeshero]

F2F: We think this might not be an issue any more, but @sydb will check more closely.

No warnings noticed in latest TEI-dev build on Jenkins. (Given that TEI_to_odd4odds is now TEI-to-tei_customization …)
