In public comments for the OGSA Glossary v1.6, Allen Luniewski made the 
following comment regarding entity and identity.  On the OGSA telecon of 
November 19, 2007 we decided that this should be submitted as a tracker to be 
considered as an update in the next revision of the Architecture document, and 
that the Glossary definitions should then be updated to reflect any changes made
.

Allen's comments:

Entity/Identity.  An entity is defined as "Any nameable thing."  This implies 
that to be an entity in the OGSA environment the thing must have a name.  Since 
the definition of "name" is very general (especially the "address" component of 
it), it is hard to say that this is wrong.  but it certainly is a bit misleading
.  When one looks at the definition of identity ("An attribute, such as a name, 
that allows one entity to be distinguished from all others.".  This seems to 
reinforce the point by implying that an entity only needs to have an identity 
and that the identity might be something other than a name.

** Additional comment from Allen in e-mail to Jem 11/29/2007: My off the cuff 
solution would be to change the definition of entity to read "Any uniquely 
identifiable thing." The idea is that an entity is a thing that can be denoted 
in some manner that gets one precisely to that thing.

Glossary 1.6: Entity - should mention that entities may have state.
