Good to know. So nothing speaks against using the fcl xml suport.

I think for my purposes (detecting type of element) it'll be enough to
read in the schema file and address the type attribute of the element
directly from the resulting dom object. I do not need to ensure
structure or completeness, the files are machine generated.

So my requirements are met, speed is not a big issue in this case.

Thank you both,
