Issues 223 [1] and 224 [2] have to do with the definition of the  
component model. I propose the following changes:

* Change the introduction text from Section 2 of part one from:

"""This section describes the conceptual model for WSDL as a set of   
components with properties, each aspect of a Web service that WSDL  can  
describe having its own property. In addition an XML Infoset   
representation for these components is provided, along with a  mapping  
from that representation to the various component  properties. How the  
XML Infoset representation of a given set of  WSDL components is  
constructed is outside the scope of this  specification."""


"""This section describes the conceptual model of WSDL as a set of  
components with attached properties, which collectively describe a Web  
service. Each subsection herein describes a different type of  
component, its defined properties, and its representation as an XML  

Components are named collections of properties that correspond to  
different aspects of Web services. Properties are unordered and unique  
with respect to the component they are associated with. Individual  
properties' definitions may constrain their content (e.g., to a typed  
value, another component, or a set of typed values or components), and  
components may require the presence of a property to be considered  

In addition to the direct XML Infoset representation described here,  
the component model allows components external to the Infoset through  
the mechanisms described in section 4.

A component model can be extracted from a given XML Infoset which  
conforms to the WSDL XML Schema [ref] by recursively mapping  
Information Items to their identified components, starting with the  
wsdl:description element information item. This includes the  
application of the mechanisms described in Section 4.

This document does not specify a means of producing an XML Infoset  
representation from a given set of WSDL components."""

* Add to Notational Conventions of part one (and others as appropriate):

"""This specification uses curly brackets (e.g., {property}) to  
indicate a property in the WSDL component model, as defined in section
