I'd like to propose replacing the text associated with the EBNF grammar in 
section 6.8.1.1:

"The following EBNF [ISO/IEC 14977:1966] grammar represents the patterns 
for constructing the request IRI"

 with the new assertion HTTPSerialization-2106:

"The {http location} property MUST conform to the following EBNF [ISO/IEC 
14977:1966] grammar, which represents the patterns for constructing the 
request IRI."

regards,
John Kaputin.

There is no WSDL assertion stating that an {http location} or 
whttp:location must conform to the EBNF grammar defined in Part 2 Section 
6.8.1.1. 

Consider the following whttp:location values, which do not conform to this 
EBNF grammar:

"/to}wn/{localname}"  (unmatched left brace)
"/town/{local:name}"  (template does not specify an NCName)
"/town/{localname"    (closing right brace is missing)

Should these be considered WSDL errors? If so, should there be an 
assertion about the EBNF grammar?  Apache Woden parses the whttp:location 
attribute and if it does not conform to the EBNF grammar the {http 
location} property is flagged as invalid, but there is no WSDL assertion 
to use for error reporting. 

Alternatively, Woden could just ignore these grammar errors and treat them 
as ordinary string content in {http location} but the problem would still 
need to be resolved when the request IRI is constructed by the message 
builder.
