[DRMAA-WG] Torque/PBS DRMAA - new optional attributes

[Daniel Templeton]

Yes, everything is optional in a JSDL document, but everything is also 
optional in a DRMAA job template.  In both cases, submitting a job from 
an empty template is result in a failure.  I think a JSDL integration 
for DRMAA would be an elegant solution to this problem.  Because JSDL 
defines an extension mechanism, we could define a JSDL-DRMAA document 
format.
