Yes. I indicated this in my original proposal that we need to find some text to point to about URI comparison. I would rather avoid specifying this in the spec and leave it to an existing standard. But eventually, this is up to applications to deal with because how to apply the XRD to an URI you have goes beyond just being able to match the pattern.

My motivation for proposing this approach was to avoid architecting a new element with children that is based on a single and very limited use case. My previous proposal had to deal with spelling out the format of each element and opened the door for interop problem with what can be included in each such as regex and wildcards. Since the use case does not require it, I feel that proposal went too far.
