LISP S-expressions is definitely not XML.  Is And Borenstein's
markup language XML?  SML is and I believe it makes a difference.

That is great for the larger companies.  They can use the full
XML and so will I for applications where i18n is a key factor.
I don't mind using UTF-8 for those occasional foreign characters
so there is no conflict.

Now, why would you mind if I used a simple subset of XML features
and gave it a name?  I do not see how that hurts those large
companies.

Try cramming full a XML parser into a toaster.  When you
got some space left, throw in a compression library as well.

You can still use XP or one of the Java parsers to parse SML since
it is XML.  I don't see where this argument is going.

I don't think the SML discussion is taking attention away
from XML Schema discussions.  Why all the hostility, Rick?
