Finding cause of Yelp 'Unable to load page' (Was: Math markup)

[Louis Luangkesorn <lluang yahoo com>]

Hello

I am working on a simulation chapter for Gnumeric docs.  To demonstrate good practice, it does have equations and greek letters.  I ended up including an alternate graphic for the informalequations so that it displays properly even when LaTeX is not in the tool chain.  It is at the point that dblatex and xmlto processes the xml source without errors to create PDF and HTML pages and my editor (jEdit) seems to think it is properly formed.

Question:  Yelp chokes on it, even though I have two different tool chains working.  Is there any way to find out what Yelp is complaining about when it returns a message box:

Unable to load page: The requested URI "analysis-simulation.xml" is not valid.

Many thanks.

Louis

I've had a long-standing intention of making Yelp capable
of doing MathML.  But since nobody's asked for it before
now, it hasn't been a priority.  Since Gecko handles it
natively, it ought to be as simple as passing any MathML
straight through the XSLT untouched.  (We could possibly
add a Content->Presentation MathML layer into the XSLT,
but I think the demand for that is close to nil.)
