Re: [xsl] [Xslt 3 Start] Use case for Function Call Invocation

["Michael Kay mike@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

If there's a use case for mixed-language programming, then there's a use case
for calling a function written in one language from a function written in
another.

It's hard to dream up good use cases for mixed-language programming, because
it's something you generally want to avoid when you can. It tends to happen
when you are integrating code that already exists, and that uses multiple
languages for historic reasons.
