I am doing parallel development on Cocoon-2.0.4 and Cocoon-2.1.
Saxon was working fine with both versions until one or two weeks ago
when it stopped working with new snapshots of Cocoon-2.1.
<side-note>
The break happened about when the fixes for XSP's not recompiling
were put in the CVS, so I have not been able to test those fixes yet
on Cocoon-2.1. On Cocoon-2.0.4 the recompiling fix almost works
for me. The cache timestamp seems to have a resolution of one minute.
It works, but slows down the coding-testing cycle. Would this be hard
to fix?

Problem details for Saxon not working with Cocoon-2.1:
Tested on 12-12-2002 Cocoon-2.1 snapshot with both:
Saxon-7.3 (patched for element bug)
Saxon-7.3.1 (baseline)
