Best regards,

Graph Store HTTP Protocol.

2.1.6 Success Responses

2.2.3 Specifying an RDF Dataset

The RDF dataset for an update operation may be specified either in the 
operation string itself using the USING and USING NAMED keywords, or it 
may be specified via the default-graph-uri and named-graph-uri parameters.

-- It may also be defined by the "WITH" keyword in the operation string 
itself



If an RDF dataset is not specified in either the protocol request  or 
the SPARQL update request string, then implementations may execute the 
query against an implementation-defined default RDF dataset.
->
then implementations **should** execute



3.1.1 SELECT with service-supplied RDF dataset

<results distinct="false" ordered="false">

  -- attributes distinct and ordered are not part of SPARQL XML Results 
Format:
http://www.w3.org/TR/rdf-sparql-XMLres/



3.1.2 SELECT with simple RDF dataset


-- RDF dataset should be written RDF Dataset



3.1.5 DESCRIBE with simple RDF dataset

<rdf:RDF ...

-- complete the namespaces





-- two occurrences of:

2.1 Sparql Protocol Interface
->
2.1 SPARQL Protocol Interface

-- the section does not exist, the link is broken



3.1.11 Long SELECT query using POST with URL encoding

PREFIX XML: <http://www.w3.org/2001/XMLSchema#>

-- prefer xsd: or xs: prefix for XML Schema datatypes




3.1.11 Long SELECT query using POST with URL encoding

<results ordered="false" distinct="false">

-- attributes distinct and ordered are not part of SPARQL XML Results 
Format:
http://www.w3.org/TR/rdf-sparql-XMLres/



Since a SPARQL protocol service may make HTTP requests of other origin 
servers on behalf of its clients,

-- I do not really understand this part:   "make HTTP requests of other 
origin servers"
