1. We don't "forward" a domain identifier.
2. We do use a domain identifier as one portion of a JID.
2. We can use the resulting JID to route XML stanzas.
3. We can compare the resulting JID against another JID.
4. We can construct an XMPP URI out of the resulting JID.
So I think:
"... this character MUST be stripped from the domain identifier before
the JID of which it is a part is used for the purpose of routing an XML
stanza, comparing against another JID, or constructing an XMPP URI."
