OK, thanks, you didn't mention it was on .NET or vb.net in particular. Looks
as if I might need to do some more testing in that environment: nearly all
my .NET testing was from C#.
If you hit other such problems, please do raise them on the saxon-help list
or forum. The .NET product is quite new so usability feedback is very much
appreciated.
