Glossary term - structure

I'm having trouble with this term as defined by WCAG:


   1. The way the parts of a Web
page<http://www.w3.org/TR/2008/REC-WCAG20-20081211/#webpagedef> are
   organized in relation to each other; and
   2.

   The way a collection of Web
pages<http://www.w3.org/TR/2008/REC-WCAG20-20081211/#webpagedef> is
   organized

We could replace "web page" with "non-web document or software" in bullet
1. But bullet 2 is problematic with regards to sets as we have defined
them. There may be no organization of the set beyond what is provided by
the file system.

Note: This term is used in guideline 1.3, SC 1.3.1, and the definitions of
"content" and "programmatically determined".

Thoughts?
