[xsl] effort to port Saxon7.x to JDK1.3

[Xiaocun Xu <xiaocunxu@xxxxxxxxx>]

Thanks for the reply on confirming the approaches.

I would love to skip straight to Saxon 7.5, but it
requires JDK1.4 and my code has to work with
WebLogic6.1 which does not support JDK1.4.

I really dreaded expanding out the variables.  After
much time hoping WebLogic6.1 would certify JDK1.4, I
finally run out of time and have to deal with it, one
single case immediately confirmed my dread.  A
xsl:statement of 251 characters, now became 970
characters, it would be a nighmare to read and
maintain.  I have about 20 such cases in my code.

Is it possible and how much effort would it be for me
port Saxon 7.5 to JDK1.3_004?

Thanks,
Xiaocun
