Although XML allows mixed content such as Kevin's:
<Feature><Name>spines</Name>, not developing at each node,
<Feature Name="Length" MinValue="0">to c.
<MaxValue>1</MaxValue><Units>cm</Units> long</Feature>
and such a document can be validated against a schema, apart from being
untidy and inelegant, mixed content can pose certain problems when
attempted to be loaded into a relational database; this is probably not
going to impress people like Gregor.

Can we agree that although mixed content XML is quite allowable, we are
going to try and avoid it in the SDD context?
