Okay, so the page name in the @page is an identifier and auto is an
identifier. I still think it the description of the @page rule should remain
as it is now and not as Ernest suggested:

Apparently  auto is a polymorphic (I had to slip that word it)
keyword/identifier that, as you suggest is a synonym for the unnamed page
context.  This allows you to say "page: auto" instead of "page: " 

It would appear that 
1. any well-formed identifier can be used a page name. 
2. the identifier auto means when used in the page property the unknown page
3. you can say something like "@page display" and "page: display" without
any ill effects

So where does that leave the original issue?

The answer depends on how auto is interpreted in the page command.  @page
auto defines a page named auto that cannot be referenced since page: auto is
the unnamed page. 

We could say that auto, when used in the context of "@page auto" references
the unnamed page, or we could say it references the page "auto" that cannot
be otherwise used--this seems wasteful and unusable.

I vote for making "@page auto" reference the unnamed page.
