Hi everyone
In XEP-0372, when references are used for "mentions", there is an
implicit assumption that the referenced text is in the <body> tag.
There are however other elements where mentions could also occur, such
as <subject>, <reason> and <text>, and some stanzas could have multiple
possible elements whose text might be referenced.
XEP-0372 provides an "anchor" attribute for the <reference> tag, which
can be used to refer to other addressable entities, to handle the case
where the reference points to something in another stanza.
I think this "anchor" attribute can also be used to disambiguate the
references in a stanza that has multiple text-containing elements. In
this case, instead of letting the anchor point to an XMPP URI, it would
only point to a fragment, meaning that the fragment is inside the same
stanza.
In HTML the fragment of a URI points to an element with the same id
attribute value as the fragment itself, but apparently this isn't a
general requirement for URIs. In this case, for simplicity, I would
however stick to that convention.
So, if you have a stanza with for example, both "subject" and "body"
tags, we can have references for both, and use the "anchor" attribute as
follows (I hope this comes out formatted properly once sent):
<message type="headline" from="[email protected]">
<subject id="subject">Attention Bart Simpson</subject>
<body id="body">Please hand in your homework before the end of the
day</body>
<reference anchor="#subject" begin="9" end="21" type="mention"/>
</message>
I think this is an elegant solution that uses the existing mechanics,
and the only further requirement would be to clarify in the XEP that the
anchor attribute can be used in this way.
I'd be happy to hear your thoughts and feedback.
Regards
JC
