dfdl:length="{/Packet_Primary_Header/Packet_Data_Length + 1 - contentLength(/Packet_Data_Field/(.*)Packet_Secondary_Header, 'bytes') - 2}"
Firstly, contentLength is a DFDL function so it needs to be in the DFDL namespace, eg, dfdl:contentLength().
Yes agree with you. We will add the dfdl: it in future releases and modify the applications accordingly.
Secondly, the first argument to dfdl:contentLength() is a path, so you are effectively still using regular expressions in path steps.
Yes. For now we are using it and expect this to become part of the standard.

Dear Steve,
Please find below the answer from our developers and example.
Note that we have updated our implementation of DFDL to be as compliant as we can at this point in time with the exception noted below.

Dear Michele,
I believe that after our DFDL compliance effort the mentioned "use of a regex in the path step of a DFDL expression" is no longer in place.
Currently the only extension implemented in DFDL4S regarding the use of regular expressions is that implementation of dfdl:contentLength is extended to support also regular expressions when specifying the node.
Please find attached a schema file example containing such extension in the use of dfdl:contentLength.
Best regards, Rui

@Michele - please can you send to the WG a schema that shows your use of a regex in the path step of a DFDL expression ?
Next call Aug 2nd
