a [*template parameter scope*](#def:scope,template_parameter "6.4.9 Template parameter scope [basic.scope.temp]") that includes the [*template-head*](temp.pre#nt:template-head "13.1 Preamble [temp.pre]") of

Each [*template-declaration*](temp.pre#nt:template-declaration "13.1 Preamble [temp.pre]") D introduces
a template parameter scope
that extends from the beginning of its [*template-parameter-list*](temp.pre#nt:template-parameter-list "13.1 Preamble [temp.pre]") to the end of the [*template-declaration*](temp.pre#nt:template-declaration "13.1 Preamble [temp.pre]")[.](#2.sentence-1)

Any declaration outside the [*template-parameter-list*](temp.pre#nt:template-parameter-list "13.1 Preamble [temp.pre]") that would inhabit that scope instead inhabits the same scope as D[.](#2.sentence-2)

The parent scope of any scope S that is not a template parameter scope
is the smallest scope that contains S and is not a template parameter scope[.](#2.sentence-3)

[*Note [1](#note-1)*:

Therefore, only template parameters belong to a template parameter scope, and
only template parameter scopes have
a template parameter scope as a parent scope[.](#2.sentence-4)
