Semantics (the graph) of feature structure should be made explicit.

XML may be used more straightforwardly to syntactically represent
feature structures, with tags as types and attributes as features. In
order to thereby deal with typed feature structures, XML schema can be
extended so as to allow multiple inheritance.

We need some guideline as to what should be attributed to schema
validation.

Relation with RDF should be discussed.

In this connection, what we may describe by feature structures should
be made explicit, too. Probably we will not use them for general
knowledge representation, though there is no technical reason
preventing us to.
