Hi developers,
I just want to provide some feedback on using 2.2.D12 in my project.
Sadly, the results and conclusions are very similar to the ones of Tom.

1) [Divergence] Processing big XML files with stylesheets that
document() other big files a lot, the processor seems to diverge
without returning any result and leaking more and more memory.
This was not so with 2.2.D3 (last release that gave me the same
results before 2.2.D12).
2) [Out of memory] I have a simple stylesheet that just process a not
so long XML list of URLs, document() them and just does a xsl:copy-of.
It quickly goes out of memory. Again, this was not so.
3) [Serialization] Serializing and deserializing some stylesheets
does not give back classes with the same semantics. I will issue
a bug report as soon as I get a minimal example.
4) [Speed improvement] This is the only improvement, but it is not very
astonishing. I can see an average improvement of 14% in the processing
time. (e.g. 19s agaist 22s for a medium-sized example on a Pentium III
bi-processor). If 1)-3) is the price to pay for 4), I fear it is not
a good trade for us.

Yes, the above is true.

Same for us.
By the way, I would like to have some explanation of the source of the
above problems. Do you think that they are all related to the adoption of
DTM? And are they all intrinsic of DTM or can they be resolved?
