[alicebot-archcomm] Additional text for the standards concerning patterns

[Dr. Rich Wallace]

Riight.  Words (of English) consist of letters A-Z and numbers 0-9. 
Wildcards consist of the single characters * and _.  Besides the space
character, no other characters are permitted in the (English) pattern
matching language.

> For the record:
>
> The following <pattern>** BALLOON</pattern> and <pattern>HE HAS THE
> BALL* DUDE</pattern> contain no wild cards and will never match a
> client's input. Am I correct that wildcards need to be documented as for
> words only?  They cannot be for a part of a word.  As a word they are a
> single character and separated from other wildcards or words by spaces.
>
> This is stated in the working draft, but is embedded in BNF notation and
> set calculus.  Given the simple nature of AIML, perhaps this could be
> spelled out in more common language in the standards document.
>
> Since the discussion has tapered off a bit, I offer to add the "cleaning
> up" stuff to the working draft so it can be forwarded to the chair for
> the adoption as the official documented AIML standard, that is,
> hopefully more than a working draft.
