The vcard-temp extension (XEP-0054) supports having URL's for the user avatar
image in a VCard using the EXTVAL element.
<!-- Photograph property. Value is either a BASE64 encoded
binary value or a URI to the external content. -->
<!ELEMENT PHOTO ((TYPE, BINVAL) | EXTVAL)>
I was wondering why doesn't vcard-based avatars extension (XEP-0153) supports
something similar for dynamic updates i.e. passing url's in place of hash of
the
binary for photo. This provides an easy way for dynamic update of user avatar
for systems using url to pass across the avatar information. Thoughts?
Thanks,
Nalin
