there was no need of deprecating xsl:assign or
fixing
a bug
where <xsl:variable name="a" select="$a+1" />
worked some time ago.
??? No version of XSL has ever allowed such a
construct.
I haven't even heard of any processor that had a bug
that would allow
such a thing. Why do you think this was allowed
previously?
Saxon has a saxon:assign extension that implements a
assignment system
but it is much easier to do this in a processor
specific extension. the
problem with assignment is that it forces a
particular evaluation order
on the code, otherwise the assignments appen in a
different order and
the processing order becomes visible. It would be
virtually impossible
to specify in general the result of assignment in
XSLT as
evaluation order is not specified. It is much easier
to specify the
result of saxon:assign as it explictly is tied to
saxon's evaluation
strategy. I've seen Mike recomend saxon:assign for
exactly this use: by
putting such variables in your templates you can get
informaation on
what saxon did, how often a template was evaluated
etc. This can be
useful debugging information, but isn't expected to
get the same result
on different processors.
