Re: [xslt] exslt functions problem

[Graham Seaman <graham seul org>]

Hi again,

I asked on the exslt list and it appears that the files below run
fine on Saxon and have no syntax problems. They also work on libxslt
if include is used instead of import, so it is a libxslt-specific bug
when import is combined with exslt functions. I'll dig around and see if I
can work out what it is, but since I don't know the code this may take
some time... ;-)
