Also it should be noted that 5.5 Provide summaries for tables. is a 'Priority
3' checkpoint.

WCAG 1.0 states:

"[Priority 3]
A Web content developer *may* address this checkpoint. Otherwise, one or more
groups will find it somewhat difficult to access information in the document.
Satisfying this checkpoint will improve access to Web documents."

the key word 'may' as defined in http://www.ietf.org/rfc/rfc2119.txt:

"MAY   This word, or the adjective "OPTIONAL", mean that an item is
   truly optional."
