Additional error condition for paged media steps? #585

Closed xml-project closed 3 months ago

xml-project commented 3 months ago

Currently we have error conditions to be raised for p:xslt and p:xquery, if the dynamic execution fails. But we do not have error conditions to be raised, if p:xsl-formatter or p:css-formatter are not able to produce the requested documents. This might be the consequence of missing fonts etc. My processor therefor raises the generic error XD0030. While writing a complex pipeline it's very difficult to generate meaningful error messages because of this limitation. The pipeline gets more complex as it needs to be because of this limitation. I therefor propose to add an error condition for p:xsl-formatter and p:css-formatter raised, if the step is not capable of producing the requested paged media document. Does this make sense?
