Sounds good to me, although I think I would also rephrase somewhat the
algorithm, à la:
* the URI's scheme component is the same as scheme; and
* if subdomains is false or if the URI's host component is not a domain
name (as defined in RFC1034), the URI's host component is the same as
host; or
* if subdomains is true, the URI's host component is either the same as
host, or is a subdomain of host (as defined in RFC1034); and
* ...
