# Test to make sure dynamically defined url-valued attributes are rewritten by
# rewrite_domains.  See mod_pagespeed_test/rewrite_domains.html: in addition
# to having one <img> URL, one <form> URL, and one <a> url it also has one
# <span src=...> URL, one <hr imgsrc=...> URL, one <hr src=...> URL, and one
# <blockquote cite=...> URL, all referencing src.example.com.  The first three
# should be rewritten because of hardcoded rules, the span.src and hr.imgsrc
# should be rewritten because of UrlValuedAttribute directives, the hr.src
# should be left unmodified, and the blockquote.src should be rewritten as an
# image because of a UrlValuedAttribute override.  The rewritten ones should
# all be rewritten to dst.example.com.
