couple of questions

Dear all,

in the algebra section of the fed document (
http://www.w3.org/2009/sparql/docs/fed/service#algebra_service), in the
algorithm, when checking if something is an IRI in the SERVICE address, I
just write "if IRI then evaluate the pattern". Is this enough? not sure
about it since the address must be an IRI.

also, in the SERVICE VAR section, is enough to specify that this section is
informative to make clear that the implementation of SERVICE VAR is optional
or should I be more specific?

thanks :)

Carlos
