Subject: Re: [wsbpel] Issue 88 - Proposal to vote
See two comments inline (mm1:...) >curdera: This is the proposal for closing issue 88. > >Replace the text of Section 6.4, starting on the second paragraph by the >following. > >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 >specified. >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. > mm1: For WSDL v1.1, is this the permanent location we want to use? >The presence of an <import> element should be interpreted as an >informational hint to the WS-BPEL processor.

" Thanks.
