Subject: Issue 88 - Proposal to vote

This is the proposal for closing issue 88.

Replace the text of Section 6.4, starting on the second paragraph by the

The <import> element is used within a WS-BPEL process to explicitly
indicate a dependency on external XML Schema or WSDL definitions. Any
number of <import> elements may appear as initial children of the <process>
element, before any other child element. Each <import> element contains a
mandatory and two optional attributes.

- namespace. The namespace attribute specifies an absolute URI that
identifies the imported definitions. This attribute is optional. An import
element without  a namespace attribute indicates that external definitions
are in use which are not namespace qualified.

- location. The location attribute contains a URI indicating the location
of a document that contains relevant definitions in the namespace
The location URIs may be a relative URI, following the usual rules for
resolution of the URI base (XML Base and RFC 2396). The location attribute
is optional. An import element without a location attribute indicates that
external definitions are used by the process but makes no statement about
where those definitions may be found. The document located at the location
URI MUST identify the definitions it contains with a URI matching the URI
indicated by the namespace attribute.

- importType. The importType attribute identifies the type of document
being imported by providing an absolute URI that identifies the encoding
language used in the document. The value of the importType attribute MUST
be set to "http://www.w3.org/2001/XMLSchema"; when importing XML Schema 1.0
documents, and to "http://schemas.xmlsoap.org/wsdl/"; when importing WSDL
1.1 documents.

The presence of an <import> element should be interpreted as an
informational hint to the WS-BPEL processor. In particular, processors are
not required to retrieve the imported document from the location specified
on the <import> element. Import elements are conceptually unordered. It is
an error if the imported documents contain conflicting definitions of a
component used by the importing process definition (as could be caused, for
example, when the XSD redefinition mechanism is used).

A BPEL process definition MUST import all XML Schema and WSDL definitions
it uses. This includes all XML Schema type and element definitions, all
WSLD port types and message types as well as property and property alias
definitions used by the process.

Schema definitions defined in the types section of a WSDL document which is
imported by a BPEL process definition are considered to be effectively
imported themselves and are available to the process for the purpose of
defining XML Schema variables. However, documents (or namespaces) imported
by an imported document (or namespace) are no considered to be transitively
imported by the process.
