perspective to TAC (Telematics between Administrations Committee)?

Esteemed DITA Technical Committee:

I notice after the fact that TAC (Telematics between Administrations Committee) sees the need to have extensible document schemas:

http://europa.eu.int/ISPO/ida/jsps/index.jsp?fuseAction=showDocument&parent=crossreference&documentID=2592

I'm wondering whether the DITA Technical Committee might want to notify TAC about the availability of DITA as an architecture for documents with extensible semantic structures.

Hoping that's interesting,
