Support Saxon10/11/12
Problem description
DAPS currently have the option --xsltprocessor=PROCESSOR to support different XSLT processors. However, Saxon 10, 11, or 12 is not supported.
Expected behavior
Saxon 10-12 supports XSLT 3.0 which might be helpful for us in the future. It's not yet decided, but to test it and make it possible, it would be nice to provide a means to support it.
Perhaps we need to add it to the daps/libexec/daps-xslt script. The saxon{10,11,12} consists of actually two packages: the saxonX package with the JAR files and saxonX-scripts with the command line saxonX and some manpages.
In its simplest form, you call Saxon like this:
saxon10 -xi -xsl:/my/stylesheet.xsl -s:xml/MAIN.xml -o:OUTPUT
The options mean:
-
-xiApply XInclude processing to all source XML documents -
-xsl:Specifies the file containing the principal stylesheet module. -
-s:Identifies the source file or directory. -
-o:Send output to named file.
You can set more options (see below). If I'm not mistaken, it is very similar to saxon6 CLI.
Action items
To support this feature in daps, we need:
- [ ] Adapt the
configuremechanism to find the respective saxon version (10 or 11. Maybe even 12 in the near future). - [ ] Adapt the
daps/libexec/daps-xsltscript to use the respective saxon script. - [ ] Extend option
--xsltprocessorto allow more thanxsltprocandsaxon. The valuesaxonshould mean: "Use any appropriate saxon version, prefer the most recent". However, the Saxon packages allow to install all of them. In that case we should allow a more specific Saxon version. Allowsaxon9,saxon10, andsaxon11. - [ ] Adapt the daps manpage.
- [ ] Add possible configuration for Saxon (perhaps as
etc/saxon{10,11,12}.conf)
Update
Saxon9 is not supported and probably shouldn't be. Version 9 supports XSLT 2.0 only, but the latest DocBook stylesheets (xslTNG) supports only XSLT 3.0.
