Serialize the document element node
instead of the root node:

    package require dom
    set doc [dom::DOMImplementation create]
    dom::node appendChild $doc [dom::document createElement $doc FOO]

    # To include <!DOCTYPE ...> declaration:
    dom::DOMImplementation serialize $doc

    # To omit it:
    dom::DOMImplementation serialize \
    	[dom::document cget $doc -documentElement]

I think that dom::c has a bug where [dom::DOMImplementation serialize]
can end up writing out _two_ <!DOCTYPE ...> declarations
under certain circumstances; I haven't looked into this yet.

Thank you, Joe.

What I really need is more XML documentation.  In fact,
I've been doing the serialize-the-document trick, and
thinking of it as a trick; apparently I wasn't so ori-
ginal.

What puzzles me, though, is that I see in the WSDL world,
for example,
  <?xml version='1.0'>
  <!-- what happened to the DOCTYPE? -->
  <wsdl:definitions xmlns:wsdl='http://schemas.xmlsoap.org/wsdl/'>
    ...
  </wsdl:definitions>  
What is *that*?  Is there some name for version-element-plus-
serialized-document?  Is there a clever way to generate it?

Quite-unrelated question:  has anyone written
  WSDL::pretty_print node
to supplement
  WSDL::serialize node
?  The former would, I imagine, indent elements proportionally
to their depth, and perhaps prettify attribute punctuation, and
so on.  Would such a thing interest anyone else, if I write it?

That's an XML Namespace declaration.  DOM Level 2 supports XML
Namespaces,
and TclDOM v2.0 includes (partial) support for DOM Level 2.
Support for XML Namespaces is part of TclDOM v2.

BTW, the Document Type Declaration is not required (it's optional
in XML anyway).  XML Namespaces do not mix at all with DTDs so it's
pretty pointless having a Doc Type Declaration when the document is
using XML Namespaces.

Again, see the '-indent' option of the serialize method.

Try:

dom::DOMImplementation serialize $doc -showdoctypedecl 0

Similarly, this method also accepts the -showxmldecl option too.
