[Implementer's Guide] Clarify implementation for the resource quantity

[GoogleCodeExporter]

We have discussed a situation that we believe valid but whose implementation is 
unclear (at least to me) at this stage. This issue is to clarify the 
implementation as part of the implementation guide (understanding that this 
does not replace the spec)

A task may be done equally by X hours of a performer A or Y hours of a 
performer B. 

We need to explain: 
- where this information will be expressed across both process and simulation 
models. 
- any implications for ordering of evaluation 

Question: 
- Is there a need for ResourceParameter associated to a Task to also have a 
reference to the Resource?

During the execution of a simulation model I would suggest that the better 
tools have a sequence of execution such that a TASK would get its RESOURCES 
then evaluate PROCESSING TIME. The implication of this order is that processing 
time can be calulated based upon both the attributes of the process instance 
being worked upon and based upon the resources selected.

This leads us to using an EXPRESSION for processing time.

This is pushed to a version 2.0 of the specification. In the mean time, you can 
always use expressions to represent the processing time to emulate this.
