Bad indent.  :)

Is this a copy?  m_data is stored using inline capacity.  It might be better to write directly into m_target.

I keep doing this; you'd have thought I'd remember this by now :(

m_data needs to be cleared in the process, to make way for the local name of the tag. Would an assign and a clear make more sense than a swap? It might make sense to leave this in the back of our minds, but for now, it's functional.

Ah, the problem is you don't know ahead of time that this is a prefix, so you need to copy out.  I'd add a FIXME to try to remove the copy.  It could get expensive if every element and attribute has a prefix.
