550 : 3,2.3 VTN and VEN invoking services on each other and 3.2.4 DR interactions are not consistent with interactions in 3.3.2.

Lines 510 and 550 and 572

In 3.2.2 Parties take on roles of VTN or VEN which is correct

In 3.2.3 VTNs and VENs can invoke services on each other. Thus VTNs and VENs change roles rather than Parties changing roles to VEN or VTN.

COMMENT WTC A Party in the role of VEN and with respect to a VTN and an EiMarketContext invokes service operations on that VTN. I don't see this in conflict.

3.2.4 needs to be deleted or updated to current terminology

COMMENT WTC needs to be updated. Figure/"Table" 10 has old names. Rest of the text seems fine.
