Excellent.  I would suggest linking them from the beginning of section
3, so that readers will be apprised of them, such as:
[[
3.1 Namespace and OWL Ontology for the SPARQL Service Description
Vocabulary
The SPARQL service description namespace IRI is:

http://www.w3.org/ns/sparql-service-description#

The prefix used in this document for this namespace is sd.

OWL ontologies for the SPARQL Service Description Vocabulary are
available in two RDF formats through dereferencing the namespace IRI:

  - Turtle http://www.w3.org/ns/sparql-service-description.ttl
  - RDF/XML http://www.w3.org/ns/sparql-service-description.rdf
]]

It would also be good to note their normative / non-normative status.

Also, I notice that the Turtle contains FOAF entries for you and Ivan:
[[
<http://kasei.us/about/foaf.xrdf#greg> a foaf:Person ;
     rdfs:seeAlso <http://kasei.us/about/foaf.xrdf>,
<http://www.cs.rpi.edu/%7Ewillig4/> ;
     foaf:name "Gregory Todd Williams" ;
     foaf:workplaceHomepage <http://tw.rpi.edu> . 

<http://www.ivan-herman.net/foaf#me> a foaf:Person ;
     rdfs:seeAlso <http://www.ivan-herman.net/foaf> ;
     foaf:mbox <mailto:ivan@w3.org> ;
     foaf:name "Ivan Herman" ;
     foaf:title "Semantic Web Activity Lead" ;
     foaf:workplaceHomepage <http://www.w3.org> . 
]]
I assume that was accidental.

Thanks!
