On a related issue, I believe there has been talk by some of requesting
replacing tei:graphic with SVG as the default recommendation.  I would like to
state for the record that I'm wholeheartedly against this.

However, it isn't for any failing in SVG (though its adoption is slower than I'd
like), that I'm against it.  Instead it is the idea of introducing yet another
namespace into TEI at all.  I love that with P5 we *can* include other
namespaces.  Currently we use the TEI namespace, the TEI Examples namespace, the
XML namespace and in our ODDs the RelaxNG namespace.  But I think we should try
to keep it only to this if possible.

However, I would be strongly in favour of the Guidelines discussing in detail
how to add in elements from other namespaces and giving detailed examples.
During the chapter discussing graphics it might be good to have a discussion and
detailed example of adding SVG.  There are many other candidates, I'm sure.  I
have no problem with us recommending the use of other embedded standards as part
of the customisation process.  But I think this should be left as customisations.

I return you to your regularly scheduled programming,
