I think the XML encoding is for RFC purposes vs what is specifically
allowed.  Have a look at RFC 3987, Section 1.4.

percent escaping for non-ASCII characters.  The use of XML-style
notation is for representing a non-ASCII character within the RFC
itself.

IMO, I think that is horrible.  The "U+XXXX" notation should be used in
RFC text.  XML character entity references should only be used in XML.
It makes the RFCs confusing to read.

Being someone who have worked with XML for a very long time, seeing such
sequences in an RFC makes me think someone was using XML to author the
RFC and the transform to plain text did not know what to do about
non-ASCII characters.
