Re: rdfa parsing problem

Meri,

I gave some more thoughts while flying back home...

Is it possible that the enclosing XHTML file, that included the example
you quoted in the mail, was not XML valid? Then the system would
automatically try with HTML5 in the default setup, and this would
explain what you experienced... (provided the HTML5 parser really
removes that <span> element, which I would expect it does)
