Description
[expr.ref]/1:
"""
A postfix expression followed by a dot . or an arrow ->, optionally followed by the keyword template, and then followed by an id-expression, is a postfix expression. The postfix expression before the dot or arrow is evaluated; the result of that evaluation, together with the id-expression, determines the result of the entire postfix expression.
"""
[expr.ref]/3: Abbreviating «postfix-expression.id-expression» as E1.E2, E1 is called the object expression...
And then the subclause describes how the result of «postfix-expression.id-expression», a.k.a. E1.E2, is determined.
But where is it described how the result of «postfix-expression. template id-expression» is determined?

Research direction
Start by reading [expr.ref]/1 and [expr.ref]/3 in the draft, then trace the subclause's rules for the result of the member-access expression. Compare the wording for an ordinary id-expression with the optional template form. Done means the specification clearly states how the template case is covered or adds the necessary cross-reference.
