Conformance #82
Description
Currently conformance notes are entered in Section 4.11, a subsection of the RDF Stream Query Language.
In W3C specs conformance notes typically come at the start of the document so that you understand how to read the document before you read it!
This section should be move to the top of the document. I would also suggest extending the use of RFC2119 to include the phrases MUST, SHOULD for the requirements section.
