If you create a gaiji (non-standard "character") and separate the 
declaration data of your gaiji from your document, your document will 
eventually become undisplayable.  The declaration data is very likely to 
be lost.

In a Japanese project called Tron, the declaration data is directly embedded 
within the document that references to it.  Probably, this is the safest 
approach.  Your document is guaranteed to be displayable.

Moreover, this approach does not lead to serious dispute.  If some 
mechanism for registering "characters" is made publicly available, I am 
sure that some character-policemen will strongly oppose.

In the context of XML, probably we need a mechanism to reference to 
some portion of an external parsed entity, which provides a collection of 
fonts.  This is very close to what you proposed, if not identical.  
I do not know if there is a good match between this approach and 
WebFont of W3C.
