XML IDREF is another XML document?

Question

Is there an easy way to use the IDREF attribute to refer to an element in another XML document? If not, any suggestions on how to do this differently? What I'm trying to do is make a digital personal table for the RPG with a table, and I want the XML document containing all the information about the characters to reference the main list of all the virtues. Sorry if this is a stupid question, I'm pretty new to using XML, or even any programming language, and just found out how much the XML process simplifies.

IDREF is a type defined to refer to other element identifiers in a single document. Therefore, you will first need to use "XInclude" to reference the external file, and then use IDREF, as it was a single file. A similar question that may come in handy is available here.
