 Upgrade from XSLT1
Dear All,
After a lot of convincing , the architectural team finally agreed to
approve Saxon9.5.  There is a bit of a relief, but I am having to make a
decision on whether we upgrade from XSLT1.0 to XSLT3.0 directly? The code
base is not very big and we are OK to rewrite to adapt to better coding
practices that come with XSLT2 and 3.

I am assuming that the coding paradigm is slightly different in XSLT3.. The
approach on how to write templates, the restrictive xpaths etc , could be
backwards incompatible etc..

I need advice on this/ Is it true that the coding approach is different
using the XSLT3 ?  I am fairly confident that the XSLT2 is a good point to
start. The only reason XSLT3 was even in the discussion was because of the
HUGE xml files. Currently we run a Sax Java splitter over the big XMLs and
run XSLT1 files over the smaller chunks. This works well. My options with
XSLT2 would be to change the XSLT1 to XSLT2 and keep remaining things
same..

With XSLT3, we may consider removing the SAX splitters, as it may no longer
be used. XSLT3 will probably take care of the memory issues with HUge XML
files.

Putting all my thoughts in,, Hopefully will get some clarity with the
expert advices from you all..
