[SML] Preliminary EBNF v0.2

[Don Park]

Here is a second cut of SML EBNF, designed to provoke
more active comment from pro-attribute folks as well
as those who want just English tag names.

Major changes are:
1. No attributes
2. No whitespace after name.
3. 'wild' name character set.
4. No '>' in CharData.
5. 'quot' removed and 'gt' added.
6. Numerical character reference is now in hex.
7. S rule is removed.

The NameChar is basically anything except '<', '>', '&',
and whitespace characters.

Note that changes in this version are not necessarily
what SML will end up as.  I am just trying to get more
feedback from folks because when people tend to speak
out more when they dislike something than when they
like something.
