DaveP and all,

I don't see any of your points.

I need means to validate XSLFOs, I describe clear usage secnarios and
reasons, and I'm talking to the XSL (XSLFI) working group.

further comments below.

I don't see why one shouldn't author XSLFO; but if that's not the
intended use of the spec; what do say about scenario 1?

What's your point here? Sure I've read those comments. The RenderX DTD
is not what I want, that's why I ask the W3C for official means to
validate pure XSLFO documents.

Also: if you use it; for what? You repeatedly question the necessity of
validation of XSLFO, but you try to validate XSLFO?

see scenario one.

I would appreciate any comments from the working group.
