My problem with the actual ref tag is that there are many ref tags
for other schemes and elements, but I don't know if this concern is
pointless or not.<br>
I would like to see this scheme more organized and not so ambiguous
data wise, but I don't know if that's technically better or if there
are actual problems with ref tag being "all over the place".<br></div></blockquote><div><br></div><div>As it stands, there is a possibility for namespace collision. That is theoretically</div><div>a problem. An object might have two references, but we've made heritage</div><div>references take the form ref:xxx=* so if the other ref is of the form ref=*</div><div>there won't be a collision. But it's also possible that both schemes want</div><div>to use ref:xxx.
