Re: [xsl] Is there an XSLT/XPath processor good enough to use in life-critical applications?

["Dimitre Novatchev dnovatchev@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

This question can be asked about any programming language and the correct
answer would be that this depends on the discipline of testing the software.

I am not sure if programs of reasonable size (as used for significant
everyday applications) can be proven correct -- e.g. using a system as
Alloy. Even if "proven" correct, there can always be error in the upper
level -- the specification of the system to the correctness prover.

Cheers,
Dimitre
