[wsrp-markup] [wsrp][markup] URI encoding.

Please read the following W3C recommendation:
http://www.w3.org/TR/html40/appendix/notes.html#non-ascii-chars

It distinguishes between the encoding of URIs from the markup in which
these URIs exist.  It recommends that URIs are first encoded using UTF8
then URI escaped prior to document encoding.

Should we just reference this recommendation?
