[1] Jose, the sentence following your excerpt above is "The term 'shape' emerged as a popular label for these constraints." I believe this clarifies that the group was not contrasting SPARQL with something like XPath, but rather SPARQL versus the high-level vocabulary of sh:minCount and sh:valueType. A new language such as a yet-to-be-defined variant of XPath or a yet-to-be-defined subset of SPARQL's FILTER expressions would arguably have the same basic characteristics as SPARQL itself. Holger
