Re: xslt-process and saxon 6.5

[Ovidiu P. <ov...@xe...>]

Hi Ben,

Unfortunately Saxon's internal APIs keep changing quite often, with no
backward compatibility. Which is OK, as a normal program is not
supposed to use those low-level, processor specific, APIs, but instead
use the JAXP API. However XSLT-process is no usual program, and relies
on very intimate details of the processor. When these change, the code
breaks or doesn't work anymore.

I noticed the problem starting with 6.4, but didn't have time to
investigate more. Any suggestion of what has changed is welcome. Of
course, a patch would really be great ;-)

Regards,
Ovidiu
