* Murray Altheim
| [referencing topics via <subjectIndicatorRef/> and <resourceRef/>]
| This does not reliably access a single <topic> element due to possible
| merging actions. 

No, but it does reliably address a topic item, and in the resulting
TMDM instance there is no way to distinguish what kind of reference
was used. In other words: for all topic map purposes it is perfectly

| And one should note that an ID link is an XML-level syntactic link
| -- we cannot rely on a Topic Map engine (obviously) to return a
| <topic> element based on a query of the contents of
| <subjectIndicatorRef/> or <resourceRef/> elements. Yes, they're
| useful, but if one is trying to query a specific <topic> element at
| the XML level in a graph structure (i.e., a bag), there's no
| substitute for an ID link.

At the XML level there is not, no. 
* Lars Marius Garshol
| If we add a note that it must be possible to refer to topics using
| only IDs, does that cover the requirements you are referring to, or
| is there more?
* Murray Altheim
| No, that is it.


| I would be interested to hear Kal's comments on this subject, as I
| know of his experience from within the code of TM4J and this I
| believe would be very helpful in making a determination over the
| correct disposition of this issue. I realize there are others who
| also could provide such guidance, but I know of Kal's in particular.

What's the issue you want guidance on?
