This is the exact same problem that was affecting my docbook site a
couple of days ago.

well, after Daniel throwed an hint, I realized you just have to declare
xmlns="http://www.w3.org/1999/xhtml"; in the 1st non-xsl tag for each 
xsl:template block.  E.g. the line above should have been:

<a href="{ href}" xmlns="http://www.w3.org/1999/xhtml";>

here I suppose you should add an <xsl:attribute> forcing again
xmlns (but I'm guessing, maybe it's a shot in the dark)

The weirdest thing is that my theory works for me, but doesn't apply 
to your example, because you get correct xmlns in your <a> tags:

> # ---- OUTPUT ---------------------------
[...]
>       <i>Generated by <a xmlns="http://www.w3.org/1999/xhtml"; href="http://www.lipsum.com/";>

This lets me believe I've not understood where the real problem is :)
