Subject: BTF - BE28 - transition_pair vs. edge_descriptor

Behavioral Task Force - Errata Submission

Assigned Enhancement Request Number: BE28
Errata Name (Description): transition_pair vs. edge_descriptor
Section: 14.5.9
Date Submitted: 970701
Requestor: Paul Graham

Status: Submitted (priority not yet assigned)

Errors found in the Verilog LRM (IEEE 1364-1995).

Details:
        The syntax box says

    edge_control_specifier ::= edge [ transition_pair { , transition_pair } ]

    transition_pair ::= 01 | 0x | 10 | 1x | x0 | x1

Yet Annex A says

    edge_control_specifier ::= edge [ edge_descriptor { , edge_descriptor } ]

    edge_descriptor ::= 01 | 0x | 10 | 1x | x0 | x1

While the two syntaxes are equivalent, what is the point of changing the
non-terminal name from "transition_pair" to "edge_descriptor"?
