Steve,

varGrp will work by listing all of the variables in the var attribute as a
string of their variable names separated by spaces.  Here is an example of
the varGrp element as used at CPANDA:

<varGrp name="VG02" type="subject" var="A1CURFOR CURRENT FORMER A2GENDER
A3AGEGP A4CBIRTH A5AETHN1 A5AETHN2 AMERIND ASIAN BLACK HISPANIC HAWAIIPI
WHITE OTHER A6QUALS1 A6QUALS2 A6QUALS3 A6QUALS4 NOFORMAL DCDANCSC DCPERFSC
BACHDEGR ADDCDNCS ADDCPERF GRADUATE FQOTHER A7GENED A8ABEGTR A8BFENGA
A8CBGPCR A8DFINC">
      <labl>Demographics</labl>
</varGrp>

That variable group displayed on CPANDA follows:
http://www.cpanda.org/codebookDB/vars.jsp?id=a00213&name=VG02&offset=0

If it'd be helpful to see the full DDI XML document, let me know & I can
e-mail you a copy.

Can anyone provide an example of varGrp/var relationships usage? I  
have 25 groups of 10-50 var elements per group. It seems natural to  
me to specify the groups in varGrp then reference the varGrp id in  
the var. Apparently this was original intent but later changed when  
reading from the following documentation excerpts.

"<!--vargrp attribute on var element removed as redundant;
use var attribute on vargrp element to
encode vargrp to var relationships -->"

"<varGrp><notes>This variable group was created for the purpose of
  combining all derived variables.</notes></varGrp>"

But how does one reference all the var id's in the varGrp? There's  
only a single attribute of var.
