This is exacly the problem I have. By the way, creating some data
beforehand can already be acomplished by creating DSSSL scripts
dynamically.

The problem I have is that I want to get an SGML document, transform
it into another DTD and while doing this I want to mark partcicular
parts of some of the (recursively nested) elements. Not all elements
in the original document have to be processed, the relevant text
parts have to be identified by regular expressions and attributes for
the resulting elements (may) come from an external SQL database.

What bugs me that these things seem so easy in Omnimark.

This proves that DSSSL already violates side effect freeness :-)

But meanwhile I found out, passing text to an external function
will still have to deal with child nodes.

Thanks for your help,
