The DRMAA specification permits the variable usage explicitly in the  
according attribute descriptions, which only implies the non-usage  
for the other attributes. The IDL spec is more precise and lists up  
the allowed attributes for PARAMETRIC_INDEX.  The Condor  
implementation allows this variable only in the path-related attributes.

I agree to take this as important feature request, and will create  
the tracker item when the initial discussion is finished.
Here is the list of job template string / string list attributes,  
which could also get support for this variable:

Already allowed for:

  attribute string workingDirectory;
  attribute string inputPath;
  attribute string outputPath;
  attribute string errorPath;


Could also be allowed for:

  attribute string remoteCommand;
  attribute OrderedStringList args;
  attribute Dictionary jobEnvironment;
  attribute string jobName;
  attribute string nativeSpecification;


Makes maybe no sense for:

  attribute string jobCategory  (since this is based on a predefined  
list of keywords)
  attribute StringList email      (since this must be a valid eMail  
address)
