I was considering whether I should allow someone to, say, append some
text to an attribute by appending it as a new text node.

Right. that's what I ended up doing.

However, it doesn't seem that clear to me that "attributes have a
single value". According to
http://www.w3schools.com/dom/dom_nodetype.asp for example, Attr nodes
can have Text and EntityReference nodes as child nodes. They can all
be serialized into a single string though so in that sense you're
right and I think I'll just treat them as such.
