Re: Updates to Abstract Syntax

Besides IPC and paths that we mentioned in the last call I noticed some
different terminology, e.g. "SHACL instance graph" instead of "shapes graph"
e.g. in the ASD it is stated: "The SHACL environment uses two inputs: a
SHACL instance graph, and a data graph" while
SHACL: "A SHACL validation engine takes two immutable RDF graphs as input,
a valid shapes graph and a data graph"

Maybe it is better to wait a bit until we publish the next SHACL PWD which
I expect to be relatively stable until do a more thorough comparison
