[memory.resource.private] says:

>     virtual void* do_allocate(size_t bytes, size_t alignment) = 0;

> > -1- Requires: Alignment shall be a power of two.

Is that supposed to be a requirement on the alignment specified by the `alignment` parameter? If so the word "Alignment" should not be capitalized and in text font.

[2016-05 Issues Telecon]

The resolution should reference [basic.align]. Jonathan to update the wording.

[2016-08 - Chicago]

Thurs AM: Moved to NAD Editorial. Will change "Alignment" to `alignment` and add a reference to [basic.align]

Proposed resolution:

1. Modify [memory.resource.private] paragraph 1 as shown:

   >     virtual void* do_allocate(size_t bytes, size_t alignment) = 0;

   > > -1- Requires: Alignment The alignment specified by `alignment` shall be a power of two.
