(1) section 3, paragraph 2:  The currency of this information plays a vital role too. I feel that we need to express 
that here especially due to the dynamic nature of Grid environment.

(2) section 3, last paragraph:  There is no mention of the persistence of these capabilities. Again for the ones that 
change - RAM and load, there should be a note on its currentness and correctness.  Also since the resource is 
responsible for advertising its capabilities, should the resource provide the algorithms for translating the high level 
requirements to XML. There is some amount of resource consumption somewhere for the translation and that is not coming 
across here.

(3) section 4.1:  change 'static' to 'relatively static'

(4) section 5.3, example 4 text:  We need a mention of some fault tolerance here. In the sense that, what happens if a 
resource is excluded from the pool and there is an advertisement still alive for that resource. And, the it is being 
considered for a job by virtue of the advertisement.  The primary nature of a grid resource pool is that it is dynamic 
in nature.
