Issue

<quote>
2.1.1 "The components directly defined within a single Definitions component
are said to belong to the same target namespace."-- what about included
components in the same namespace?

Discussion

Actually, Part 1, Section 2.1 is inconsistent on this topic:

Section 2.1.1 The Definitions Component [1] - says that "The set of
interfaces/binding/services/etc. available in the Definitions component
include those that are defined within the component itself and those that
are imported and/or included."

Section 2.1.1 The Definitions Component [1] - declares that components
belong to the same target namespace: "The components directly defined within
a single Definitions component are said to belong to the same target
namespace".

Section 2.1.3 Mapping Definitions' XML Representation to Component
Properties [2] - brings components from the included and imported
namespaces:

"{interfaces}	The set of Interface components corresponding to all the
interface element information items in the [children] of the definitions
element information item, if any, plus any included or imported Interface
components (see 4. Modularizing WSDL descriptions).	

{bindings}	The set of Binding components corresponding to all the
binding element information items in the [children] of the definitions
element information item, if any, plus any included or imported Binding
components (see 4. Modularizing WSDL descriptions).	

{services}	The set of Service components corresponding to all the
service element information items in the [children] of the definitions
element information item, if any, plus any included or imported Service
components (see 4. Modularizing WSDL descriptions)."


Proposed Resolution

Re-state in simple terms: the Description (LC43) Component is a container
for Interface, Binding, Service, Element Declaration, Type Definition and
Extensibility components. That's it.

Include and import are at a different level, composition. This level is
different from the component model. Composition is clearly answered in the
mapping section.
