[DDI-SRG] DDI bug 225 - need your advise

[Wendy Thomas]

Herve,

Nothing like and an abrupt jump into the meat of the matter :) If you 
hadn't guessed by now we'd like your help with this to ensure we are 
putting in what is needed. We were discussing this today and had a 
question about whether our solution was sufficient to provide machine 
actionability.

ExternalAid is a means of attaching a document, video, image, audio, or 
multimedia to a question item. Its used as in "After viewing this video 
clip how did you feel about...." where ExternalAid provides the reference 
information for the video clip. Right now it is simply the content of 
r:OtherMaterial.

Hope this clarifies my earlier request
Wendy
