must specify "encoding" attribute in DTD. Why?

Hi,

Why is it required to specify the encoding pseudo attribute in
a DTD? For example, it is OK to have:

<?xml version="1.0" encoding="ISO-8859-1"?>
<!ELEMENT ...>

But it causes Xerces to report an error of "more pseudo attributes
expected" if it is:

<?xml version="1.0"?>
<!ELEMENT ...>

Where is it mentioned in the W3C XML recommendation? Thanks
for any pointer!

I'm not sure; maybe it was thought that there was no point to it if
it didn't specify the encoding, but it might be useful just for
the version number.

You should always specify encoding. Otherwise, exchanging information
further than between your couple of computers :) eventually gets
somebody's headache.
We see all the time here in Denmark that some people still think ASCII
covers everyting (it's insufficient for anywhere but America), and, even
worse, the implicit assumption that everything is ISO8859-1.

That's an exaggeration: ASCII is quite sufficient for most documents
in English. On the rare occasions that I might want to put, say, a
pound (sterling) symbol in an XML document, I can use a character
reference.
