SWObjects doesn't implement property paths, but apart from that, here are the data-sparql11 test result diffs. They are annotated (leading character '#' after the patches) here and attached without annotations. I believe these patches correct the existing tests.

There's one more which I would have a hard time explaining in a SPARQL tutorial. How does the graph ?g in subquery03 simultaneously constrain the subselect's BGP to be in some (all, really) named graph without constraining the ?g to be that graph?
[[
select ?x where {
graph ?g {
{select ?x where {?x ?p ?g}}
}
}
]]
Having subselects ignore containing graph constraints seems like a more consistent and predictable language. Thus the above {?x ?p ?g} would be matched against the default graph. If the user wants it to be in a named graph, they can utter the graph constraint. This is trivial to implement (similar to what one does with nested name graphs) and IMO, far more clear to readers/writers of SPARQL queries, as well as 3rd party rewriters.
