RE: [Tclhttpd-users] question on charsets

[Shawn K. <sha...@ea...>]

I don't think it follows that it is true in an xml document type declaration
as well.  Is the document type declaration used for other purposes such as
validation?

That's correct -- and it *is* standardized.
From section 5.2.2 of the html spec:
----------------------------------------------------------------------
To sum up, conforming user agents must observe the following priorities
when determining a document's character encoding
(from highest priority to lowest):
- An HTTP "charset" parameter in a "Content-Type" field.
- A META declaration with "http-equiv" set to "Content-Type"
  and a value set for "charset".
- The charset attribute set on an element that designates
  an external resource.
