Adrian made the suggestion some time ago of using the fo:declarations 
element to override configuration on a per-document basis:

If some mechanism were to be implemented inside the FO file, I think 
this approach would be a good one. It’s not as fine-grained as a PI (no 
means to say “from now on, do this”), but I share Jeremias’ feeling 
about PIs.

Re: Update: XML JARs

2008-02-20 Thread Vincent Hennebert
I get the same kind of errors on my Linux box. I don’t understand why 
the error under Java 1.4 does not occur when xercesImpl.jar is added to 
the classpath, since AFAIK we don’t trigger the endorsed mechanism, so 
the default SAX parser implementation shipped with Java should not be 
overridden.

I guess the simplest is to keep with the status quo, or with your 
solution #2 if you feel like implementing it. However, I would put only 
serializer and xercesImpl in the endorsed/ directory, since like 
I explained [1] I’d consider the other two as regular dependencies 
(classes not available in the standard library).

(That said, newbies will probably download the binaries instead of 
having to fiddle with the source files.)

FWIW: running FOP out-of-the-box to me is also a much more important concern 
than removing those JARs, so I'm in favor of keeping the status quo for now.

Probably very few - and if fop does not use them, it is not consistent
to start using them.

This idea sounds really reasonable and consitent. Please note however,
that XSL fo specified (color-profile)+ as content for fo:declarations at
some point, which would make some documents non-conformant. So +1 for
this one :)

Probably due to the services directory in xercesImpl.jar, which points
to Xerces as the SAXParserFactory implementation.

From my experience, a mechanism saying “from now on, do this” is
likely to confuse a non-trivial amount of users.

I think there should be the following hierarchy (which is already
complex enough)
- config file
- overridden by command line arguments
- overridden on a per document basis by extension elements in the
  fo:declarations section
- overridden on a per element basis by extension attributes on the
  element
- overridden by specific "force" command line arguments ("force
  all warnings/problems to be fatal" may be the only one of this kind)
