[xep-support] Validation fails

[Nikolai Grigoriev]

Hi Jerry,

It's a difficult issue :-). By the very design of XSL, nothing 
precludes specifying unused inheritable properties anywhere 
in the object tree; so I have no right to claim that this is 
incorrect XSL. However, it is hard to believe that a no-op
attribute is deliberately added to the stylesheet only to make
it bigger :-). Whatever the intended meaning of fo:region/@font-size 
is, it cannot be achieved this way - and therefore it is probably 
a bug. That's why we are issuing a validation error.

There are other questionable points in StyleVision 5.3:

  - it puts margin-* attributes on side regions (fo:region-before/after), 
    which is not permitted by the spec (this one is definitely a bug);

  - order of regions does not follow the content model 
   gven in the Recommendation (this is more an inconsistency
   than a bug: we issue a warning).

It's a configuration problem. Looks like StyleVision expects formatter 
output to be like FOP, and treats any other diagnostics as errors. If you
turn off all output from XEP, it works. For instance, I have XEP 
installed in C:\XEP under Win2000 and the following string 
in Tools->XSL-FO Options->FO Processor in Stylesheet Designer:

C:\XEP\xep.bat  -DVALIDATE=false -quiet

PDF preview works for me.

It means that StyleVision is probably tuned for FOP :-).
