Clarifying assertion for HTTP Location

Part 2 section 6.7.1.1 Construction of the request IRI using the {http
location} property.

This section contains the assertion:

"Strings enclosed within single curly braces MUST be element names from the
instance data of the input message."

I assume 'input message' here refers generically to any input data for the
HTTP request (i.e. to a WSDL input, output or fault message element).   To
make this clearer and to keep it consistent with the description at
hyperlink "instance data", perhaps you could restate this something like:

"Strings enclosed within single curly braces MUST be element names from the
instance data of the input, output or fault message."
