By "template" you mean some code that gets converted to HTML by some
software, right? Then there's no such thing as validity or invalidity for
the template, unless it is describable in SGML or XML and you have defined
a DTD for it. So there's no "should also be valid". Validity is a property
of the generated HTML document only.

The character "_" is not unusual. It is simply not allowed as the first
character of an ID value, and the id attribute is declared as being of
type ID. Do whatever needs to be done to make the id attribute value
conform to the required pattern, which is described in prose at
(The key issue is that it must begin with a letter.)

Around what? I'm pretty sure you can fix the error, but if you need help
with it, try asking on a forum devoted to using ASP, and explain in
sufficient detail the ASP code you are using.

The real meaning of the validation logo is just showing off, often
even falsely; for a more detailed explanation, see
But technically, what you are asking is "can I claim to conform to some
rules when I don't actually conform, if only I think I've tried hard"?
