Thank you Michael,

I realy missed upgrading to SAXON 4.2.
I now upgraded to SAXON 4.5,  tested
it and everything works fine.

Shame on me not checking your
page for months - but there was no
bug reports!

Rgds.Paul.

PS. The upgraded DTDGenerator Frontend
runs at  http://www.pault.com/Xmltube/dtdgen.html
