Re: [xsl] replacing <!DOCTYPE> with <?xml-model?> in XSLT

Hi Martin,

The processor is Saxon inside Oxygen; I am running this as an Oxygen
refactoring operation.

Oxygen compares the result against the input, then tries to minimize the diff
footprint due to serialization differences. I suspect this
bminimize-the-serialization-differencesb processing might be responsible
for me seeing a different behavior in Oxygen versus your fiddle.

Thank you for having a look!

If the <!DOCTYPE> gives you a problem when you fiddle with this, you could
probably remove it and just play with the PI addition.

AqxuNdjRH4$> using the XHTML DOCTYPE instead, as Saxon has that internally in
its resolver data. The result I get is e.g.

so the PI is where you want it.

I don't see why you would need <xsl:output doctype-system=""/>, the input
DOCTYPE is not copied as it is not part of the XSLT/XPath data model.
