Review the enclosed example.  Test1 shows the issue.

The trace shows:

(Level 5: Offset 217, len 5, comp 2 of 4, #1, DI 000000000009:)
Data at offset 217 ('>Paul') was found to be of TYPE
   X'0010' (ElemDecl Name Element DTD).

...so one might assume that the reference the Name field (from the first Group) you would use:

=Value:ElemDecl Name Element:Global:In1

However, you will note that ALL the data first goes into the root object, and therefore the rule needs to be:

=Value:ElemDecl Name:ElemDecl Group:Seq Comp:ElemDecl Root Element:Global:In1

...as demonstrated in Test2.    (I've colour coded the rules above for easier reading)

Thank you.
