PSI Meeting Minutes

1) WSDL with strong typing
	- Discussed element defined by union - Unioned restrictions should
have the same type to make sense for the base element.  PSI is OK with the
existing semantic model definitions - with the exception of
DocumentFormatWKV - since this needs to be a string, other restriction
needs to be a string, not NMTOKEN.

2) Discovery update
	- Ira discussed Mobile Addhock Network - issues a Service Request
rather than a Route Request.  SLP service types.  Nokia is developing the
specification.  ietf home page www.ietf.org - working groups mana...  This
would be deployed in smaller ad-hock networks in accesspoints, etc..  Could
this be deployed in an enterprise?  A big enterprise would run into
problems...  Mane give a route as well as a URL..
	- Last week, discussed the possibility of having a PrintService
published during DHCP configuration.  

3) Review 0.94a Mandatory/Optional
	- QueryEndPointsInterface
		- Client - Mandatory unless administratively pre-configured

		- QueryInterfaceEndPoint & QueryInterfaceWSDL - Client One
is mandatory unless administratively pre-configured

	- QueryInterfaceWSDL
		- this method returns a URL that refers to the WSDL that
defines what the service ACTUALLY supports, not simply the standard PWG
definition.
		- For example, target devices could return a URL to the
WSDL that is hosted by the manufacturer, and not on the printer, or to the
WSDL that is configured by the administrator.


	- ServiceCapabilitiesInterface
		- GetTargetDeviceElements - Discussion around making a
TargetDevice validate the targetDeviceIdentifier, and throw an exception
(New exception - InvalidTargetDeviceIdentifier) if not correct.
			- TargetDeviceIdentifier
				- Client to TargetDevice - Mandatory
			- requestedElements - If NULL, returns all elements
supported


	- JobControlInterface
		Client - Conditionally mandatory - If you want to create a
job, must use the interface.

		CreateJob Method
			TargetDeviceIdentifier - same as above
			deliverToTargetDevice - Client to TargetDevice -
Mandatory, must be TRUE

			requestedTargetDeviceDataType - Client to
TargetDevice - optional.  If provided, validated


		Pick up on AddDocumentByReference next time.
