If you do this you probably would want to scope the keyword topic's base
names so that they aren't accidentally merged. <resourceRef> links are

used to point something considered as an actual resource, so in your 

example, the topic *element* would be considered as a resource. While not
strictly incorrect, it's pretty confusing; you could put an ID on the
<resourceData> element and point to that instead, since it's the content
of the <resourceData> that is the resource, not the <topic> wrapper.

You also probably don't want to require custom topic map processing
functionality. Pointing to an XML element within an XTM document and
expecting to obtain its DOM Text node as a resource is probably not
asking too much.
