There is a difference with static alternate pages, and pages that are
generated on the fly off the same source document.

Alternate page does not mean a different parallel website,  it means a
different XSL or interpretation of the same source document
For example, not all XML pages are marked up in a way that user
technologies know how to handle -so  XAG (XML Accessibility Guidelines)
advice (if I remember correctly) that you need an XSL or version if your
site, that creates markup in a WCAG useful and conformant manner.

The concerns about alternative versions aging is not problematic  if
different versions:

1.	work off the same source document
2.	are easily accessed by the main version,
3.	contain ALL the information that can be found on the main page
(no information is lost)
4.	are automatically generated as the main source document is

Keep well and all the best
