The grammar for constrained-template-parameter given in 13.2 [temp.param] paragraph 1 is:

constrained-template-parameter:

::

_opt nested-name-specifier_opt concept-name

...

_opt identifier_opt

::

_opt nested-name-specifier_opt concept-name identifier_opt constrained-default-argument_opt

::

_opt nested-name-specifier_opt concept-name

<

simple-requirement-argument-list

> ...

_opt identifier

::

_opt nested-name-specifier_opt concept-name

<

simple-requirement-argument-list

>

identifier constrained-default-argument_opt

The identifier naming the parameter is optional in the first two productions but not in the latter two productions. Is there a reason for this discrepancy?
