shapes-ISSUE-181: SHACL conformance for partial validation reports [SHACL Spec]

http://www.w3.org/2014/data-shapes/track/issues/181

Raised by: Jose Emilio Labra Gayo
On product: SHACL Spec

When preparing the test-suite, it is not clear to me if we have to declare/check all the validation reports that must be returned by a SHACL processor or just a true/false.

The spec contains the following phrase:

"The validation process returns a validation report containing all validation results. For simpler validation scenarios, SHACL processors SHOULD provide an additional validation interface that returns only true for valid or false for invalid."

A SHACL processor that wants to handle use case 3.31 (https://www.w3.org/TR/shacl-ucr/#uc34-large-scale-dataset-validation) about validating very large datasets may decide to return just the first violation it finds, instead of continue processing/generating all the possible violations. 

Is that SHACL processor conformant with the spec? In that case, when defining the test-suite, is it enough if we just declare true/false as the possible result of SHACL validation? Or if a SHACL processor returns just the first violation report that it finds?

In any case, I think the spec should be more clear about when a SHACL processor is conformant or not if it doesn't return all the violation reports and just returns the first one or signals that there was an error.
