[jdt-core-dev] Add JavaDoc tag and contribute to index

[Henrich Kraemer <henrich.kraemer@xxxxxxxxxx>]

I posted that to the newsgroup without response. Perhaps
this is a better place. 

(How) Can a plugin do the following? 
1. Insert a specific JavaDoc tag into the comment of classes, operations
and perhaps other elements to link the code with external information.
The tag would contain some sort of ID. 
2. Contribute to the index, such that one can quickly locate all Java elements
associated with a particular ID? 

The JDT Core milestone plan states "rewrite the indexing infrastructure,
and extract it into a generic plug-in." 

I understand that this means this was committed to. Has this already happened?
Would that change the approach to do this?
