The SPARQL 1.1 specification does have adequate formal description of
SPARQL 1.1 features, as far as I can tell.   So that is not the problem
that I see.   What I see is the CG coming up with a laundry list of
proposed new features without any notion of how to define or implement them.

PS:  I said that the SPARQL 1.1 specification has an adequate formal
grounding.  That doesn't mean that this grounding is everywhere reasonable,
or implemented, or even cohesive.  On the contrary, there is at least one
major part of the SPARQL 1.1 specification that is unreasonable,
unimplemented, and not even cohesive with the rest of the spec.  I was
hoping that this CG would look at  failures in the SPARQL 1.1 spec and come
up with suggestions on how to solve them, but this doesn't appear to be
part of the draft charter.

Boris, and don't forget what I have mentioned earlier, there are a number
of features that are already wideley available in implementations or are
simple to add to any runtime. Here the community could benefit from
standardization. It's also explicitly mentioned in the charter of this
commnity group: "features found as extensions to available triple store"

Peter, while I have a generel idea what you are refering to here can you
please state what kind of formal description is currently lacking in SPARQL
1.1 and what would you like to see in a future SPARQL 1.2 specification.
