Category not working when using entity reference to nodes

Hi,
I have a site where I'm using a entity reference to other content type as a sort of categorization.
I'm trying to create a RSS feed and use this entity reference for Category. It is partially working.
I mostly get only the <category domain="[node:url]" />, but the node title is never used. And if a taxonomy term with same ID exist, the term title is used.

Could there be:

• support for nodes (or other entities)?
• or some description only taxonomies are supported?

Thanks
