OW Object definition question

Environment:

    OW 8.1.1.8

    Linux RHEL 5

As part of the definition of an object or in an <ObjectRef> XML tag is an attribute called "id". More often than not this "id" is some ugly hex string like "id='#ID#9D67-:7D92507B821:09AFD972-:4C30BB4E783F1118'". I've noticed that you can change this for something humanly readable like "id='#ID#Resource:Test Resource'". OW doesn't seem to care. Netbeans on the other hand seems to be quite picky about matching up these "id" values.

I also have object that do not have any "id" attribute, yet they seem to work just fine.
