===============================================================================
============================== Combined Draft a  ==============================
===============================================================================
Copied pass 7 product volume, product flow model, production report and well test schemas.
Copied draft well completion, wellbore interval and production string schemas.

Modified to be based on (soon to be released) WITSML v1.3.1.
Split out the unmodified WITSML v1.3.1 components to folder /witsml/.
Retained additions unique to each object in files like typ_dataTypes_OBJECT.xsd 
(implies that the addition would ultimately be added to the WITSML file typ_dataTypes.xsd).

Changed namespace to "http://www.witsml.org/schemas/Proposed/Combined/131a".

Changed name of composite to WITSMLComposite.*
Deleted the redundant installation element from co_productFlowModel.*

>>>>> PRODUCT FLOW MODEL
In model:
	Made comment optional.*
In network:
	Made comment optional.*
In port:
	Added a timestamp to port connections and allowed the connection 
	to recur but only one active connection is allowed.

>>>>> PRODUCT VOLUME REPORT
	Redefined installation so that is is not part of the identity of the report.
	Added contextFacility.
	Deleted cs_refProductFlowPort.xsd.*

>>>>> PRODUCT OPERATION REPORT
	Redefined installation so that is is not part of the identity of the report.
	Added contextFacility.

>>>>> WELLBORE INTERVAL
	Eliminated a set of intervals in favor of a generic interval with a kind. This eliminates
	the problem that the set would be a growing object.
	Eliminated cored interval because of redundancy with conventional core and sidewall core.
	Eliminated dst interval because of redundancy with well test.
	Eliminated squeezed interval because of redundancy with cement job.
	Eliminated the openhold 'type'.



============================== Changes for pass 7 ===================================

Conceptual changes:
	Changed the terminology from 'pfnu' to 'product flow'.
	Connect ports to one node instead of to ports. All ports that are connected to the same
	node are connected to each other. There is no pressure drop across ports or between
	ports connected to the same node. There can be a pressure drop between ports 
	internal to a unit. The assumption is that steady-state fluid flow exists.
	Split model into model and network:
		A model is composed of many networks but only one network 
		represents the overall model. All other networks represent a Unit
		within another network (i.e., you can 'drill down' to more detail).

Added absoluteMinPres to cs_pressureTemperature.
Added a production operations report object.
Added an overall composite schema that includes well test, production volumes 
and production operations.

======================== Changes for v1.3.0a (well test)  ============================
Incorporated the wellTest schema from the witsml proposed area.
Modified to base it on WITSML v1.3.
Deleted 'otherData' elements. 
Eliminated generalMeasure. 
Used witsml:timestamp instead of xsd:dateTime.
Used measureDepthCoord instead of lengthMeasure for md.
Used volumePerVolumeMeasure instead of xsd:double for GOR.
Added names and uids to obj_wellTest.
Put choice around fluid, production and injection test data and moved-up common elements.
Added choke size, previous report date and last valid report date.


============================== Changes for v1.3.0a ===================================

Added enumerated values.

Removed the concept of the quantity qualifier after determining that the qualifiers
were actually qualifying either the product (net oil, gross oil) or the 
period (report start, report end). The qualifiers were moved to the appropriate kind.

Moved some characteristics from facility to product and added others. 
The characteristics of the product must be able to change from usage to usage.

Changed the naming system to 
	http://www.witsml.org/schemas/ProductionReport/130a
so that we can keep track of which files and examples go with with which version.
