ODD to ISO Schematron conversion fails after TEI P5 4.9.0 update

[SebastianKohler]

Since TEI P5 was updated to version 4.9.0 and the stylesheets to 7.58.0 I'm unable to convert my TEI customization from an ODD document to ISO Schematron constraints.

TEIGarage gives the following error message:

Error: class pl.psnc.dl.ege.exception.ConverterException
Errors were reported during stylesheet compilation

The ODD document is valid and I can convert it to a compiled ODD document with TEIGarage without errors. The compiled ODD is, however, not valid because the xml:base attribute on the document root is empty:

<TEI xmlns="http://www.tei-c.org/ns/1.0" xml:base="">

Oxygen informs me that

value of attribute "xml:base" is invalid; must be a URI matching the regular expression "\S+"

I can convert my ODD document to an XSD schema without errors, and the schema works as intended. It's just that the conversion to Schematron fails.

How can I find out if there is an issue in my ODD, or is there an issue in the updated stylesheets that TEIGarage uses?

Thank you for opening this issue, I will have a look into it

I'm not sure but I was recently facing a similar(?) error with the odd2schematron conversion: TEIC/Stylesheets#729

@SebastianKohler could you try to transform your ODD on the command line and report your findings (along with your Saxon version)? Or could you share your ODD file for us to test?

[SebastianKohler]

@peterstadler My ODD file is here: https://github.com/slsfi/digital-edition-xml-resources/blob/main/tei-odd/tei_sls_master.odd

I appreciate if you could test it. I tried to transform it using https://github.com/TEIC/Stylesheets/blob/dev/odds/extract-isosch.xsl in Oxygen (Saxon-EE 12.3) and got an error from line 143 in the xsl-file: Internal fatal ERROR: Unable to determine the language (i.e., @xml:lang) of any constraints..

[peterstadler]

So, here are my findings:

1. converting your ODD to a compiled ODD via TEIGarage: works!
2. extracting ISO Schematron constraints with Saxon9 and current dev version of Stylesheets

# java -jar ~/lib/saxon9he/saxon9he.jar -s:/Users/pstadler/Downloads/tei_sls_master.xml -xsl:/Users/pstadler/repos/Stylesheets/odds/extract-isosch.xsl              ~/Downloads
Static error at xsl:template on line 464 column 94 of extract-isosch.xsl:
  The path in a pattern must contain simple steps
Errors were reported during stylesheet compilation

does not work!
3. extracting ISO Schematron constraints with Saxon12 and current dev version of Stylesheets (and adding a language parameter)

java -jar ~/lib/SaxonHE12-5J/saxon-he-12.5.jar -s:/Users/pstadler/Downloads/tei_sls_master.xml -xsl:/Users/pstadler/repos/Stylesheets/odds/extract-isosch.xsl lang=en

works!

So, the quick fix for you @SebastianKohler might be to add the lang parameter to your transformation in Oxygen.

For the TEIGarage it seems we'll need to strive for a Saxon update.

[SebastianKohler]

Thank you @peterstadler! The quick fix worked.

Ummm … I think TEIC/TEI#2684 and TEIC/romajs#177 may both the same error as this issue. At least, it may be if the Stylesheets/bin/ type commands are being used.

I think someplace bin/teitoschematron is being called when bin/oddtoschematron is what is intended. (The difference is that the former does not do ODD processing first unless it is handed the --odd switch; the latter does ODD processing by default.)

I think this in part because when I issue bin/teitoschematron using @SebastianKohler ’s tei_sls_master.odd as the input file I get the exact same error. (Which is quite reasonable, that file does not have an @xml:lang attribute to let the poor processor know which constraints it should be extracting.)
But when I issue bin/oddtoschematron on the same file I get the expected output, a Schematron file that looks like it has a subset of the TEI Schematron constraints. (Probably the subset that come from the modules that are included in the customization, but to be honest, I did not check.) This works because the processed ODD does have an @xml:lang that asserts it is in English. (Which it seems to be.)

[peterstadler]

Just a quick test after TEIGarage update v1.2.5 but the error still occurs.

How to reproduce:

curl -LO https://github.com/slsfi/digital-edition-xml-resources/raw/refs/heads/main/tei-odd/tei_sls_master.odd
curl -X POST -F "fileToConvert=@tei_sls_master.odd" https://teigarage.tei-c.org/ege-webservice/Conversions/ODD%3Atext%3Axml/ODDC%3Atext%3Axml/isosch%3Atext%3Axml/
