If you have a document like this, and no DTD or schema:
<foo>
<bar/>
</foo>
then in the resulting DOM, node "foo" has 3 children:
* a linefeed (note: not "empty")
* a bar element
* a linefeed (note: not "empty")
If you don't want this behaviour, you can provide an XML schema which
specifies that node "foo" has element content only; the parser then
knows that all whitespace within foo can be ignored. I think a DTD can
also be used to specify element-only-content but am not absolutely sure.
Without a DTD or Schema, the parser can't throw away text within foo
(even whitespace) because it *might* be important to the calling
program.
