in thread generating A NAME tags in HTML output

ID and NAME tokens must begin with a letter ([A-Za-z]) and
may be followed by any number of letters, digits ([0-9]),
hyphens ("-"), underscores ("_"), colons (":"), and
periods (".").

OK, assuming that the NAME in A NAME is a NAME token in SGML, that pretty much covers it.

    ...may be followed by any number of letters...

    I assume that with "letters" you mean 'a' to 'z'? (There are many other characters that many, many people consider letters.)

    Update: That's when I finally read the post I answered. Doh! Me bad. Forget it.

      It uses plain ASCII characters, letter meaning [A-Za-z]. SGML, being 30 years old, obviously predates Unicode, and was contemporary with 7-bit character sets and bank-swapping concepts that grew into the horrible mess known as ISO-2022.

      I don't know if XML extends this, allowing other characters in "identifier" -like tokens. C and C++ lists all legal letters and idiographs in all character sets permitted in identifiers; I don't know if Perl references a formal standard, but it also allows Unicode characters in symbol names. I good first appoximation is to use the Unicode "properties" to pick letters, letter-like symbols, etc.
