Just a quick q (I am new to WSDL). When I create a new WSDL doc, why are
all elements within the WSDL prefixed with wsdl: ?
I am reading some docs on WSDL 2.0, and they state that if there is a
desecription element defined with the wsdl 2.0 namespace defined, there is
no need to prefix all the elements.

Thanx for the clarification ahead of time.

The prefix is there because WSDL is an XML language that uses namespaces.

You're correct that the elements do not have to be prefixed. If the WSDL
namespace is specified as the default using xmlns="" all non-prefixed
elements will be in the WSDL namespace. In this case your definitions
element will look something like

<definitions name="Echo"
targetNamespace="http://www.example.org/Echo/"
xmlns:tns="http://www.example.org/Echo/"
xmlns="http://schemas.xmlsoap.org/wsdl/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">
...
</definitions>

as opposed to the following editor default

<wsdl:definitions name="Echo"
targetNamespace="http://www.example.org/Echo/"
xmlns:tns="http://www.example.org/Echo/"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">
...
</wsdl:definitions>
