Two small issues in WD-12

At Line 382, "... it can be mapped to an operation provided by a Node Template, it can be mapped to an operation provided by a Relationship Template..."
According to the spec, an operation is provided either by a Node Type or a Relationship Type. So I think the sentence should be like this: "... it can be mapped to an operation provided by a Node Type, it can be mapped to an operation provided by a Relationship Type..."

At Line 547, "A process model can contain tasks (using BPMN terminology) that refer to operations of Interfaces of Node Templates or any other interface (e.g. the invocation of an external service for licensing);"
This sentence has the similar issue. And in the current spec, Relationship Types also provide operations. The sentence should be like this: "A process model can contain tasks (using BPMN terminology) that refer to operations of Interfaces of Node Types , Relationship Types, or any other interface (e.g. the invocation of an external service for licensing);"
