Endpoint sequence requirements

A type X meets the EndpointSequence requirements if it satisfies the requirements of Destructible (C++Std [destructible]) and CopyConstructible (C++Std [copyconstructible]), as well as the additional requirements listed below.

In the table below, x denotes a (possibly const) value of type X.

Table 12. EndpointSequence requirements

expression	return type	assertion/note pre/post-condition
`x.begin()` `x.end()`	A type meeting the requirements for forward iterators (C++Std [forward.iterators]) whose value type is convertible to a type satisfying the `Endpoint` requirements.	[`x.begin()`,`x.end()`) is a valid range.
