Agree.

GRDDL will be important, once people in the XML world start really 
groking the advantage of semantics. It will allow them to participate 
at a minimal cost.

GRDDL has already had one very useful effect: it has completely made
the XML/RDF wars disappear. GRDDL is in the back of my mind whenver
someone says they have a new XML syntax. (I think they are doing more
work than they would need to, but it's not worth my time explaining
this)

One problem I see with the XSLT transform method is that it seems very 
slow. I'd rather have a transform directly to RDF such as the new
XSPARQL member submission

  http://www.w3.org/Submission/xsparql-language-specification/

I think GRDDL allows for that, btw, but as I have not used it yet I 
don't want to say. This type of transform would make GRDDL (or something
similar) very efficient, as one could then convert any format directly
into a graph for inclusion into a quad store.

As with a lot of things the time between the establishment of a standard
and its adoption can be very long. In the semantic web community we know 
this all too well.
