I have a question/observation about XSLT.
If we look at the equation, where :
XML(1)*XSLT(1)=Output(1)
as well as
Output(1)/XSLT(1)<>XML(1)
we find that XSLT in fact is an (effective?) one way encryption scheme.
I doubt it's a very strong encryption scheme, though that no doubt depends
on the stylesheet. I tend to think of a stylesheet as a function output =
xslt(input). And it's certainly a one-way function.
Is this intended behavious, should i t be so, and is this addressed in XSLT
2.0?
I think a reversible transformation would be a very different animal, and
would require a much more restrictive language. For example, how could you
possibly reverse the effect of the stylesheet:
<total xsl:version="1.0" xmlns:xsl="..." value="{sum(//item/@value)}"/>
