change element MaterialSublotProperty to MaterialLotProperty for MaterialSubLotType #43

Background

For MaterialSubLotType, Change MaterialSublotProperty to MaterialLotProperty.

 <xsd:element name = "MaterialSublotProperty"      type = "MaterialLotPropertyType"      minOccurs = "0" maxOccurs = "unbounded"/>

Change to 

 <xsd:element name = "MaterialLotProperty"      type = "MaterialLotPropertyType"         minOccurs = "0" maxOccurs = "unbounded"/>

Both material lot and material sub lot are referring the same material lot property model. Thus in ISA-950002, there's no such model called MaterialSublotProperty, so here the element name changed from MaterialSublotProperty to MaterialLotProperty to reflect the property type.

No, the sublot property already uses the property type, but it is a sublot property, not a lot property. See in section 5.7.8 "Material sublots may have sublot specific properties. " and "EXAMPLE 1 Material sublot properties can be RFID tag IDs or other identification properties, such that each material sublot has a different property value."

The ISA 95 Part 2 text is inconsistent. The text in 5.7.8 says "Material sublots may have sublot specific properties.", but Table 72 used the name "Material lot property" as the role. However Table 72 also has the definition of "The material sublot properties map to a corresponding material lot property.":

Changed to use the element name MaterialLotProperty in the MaterialSubLotType. Issue closed.
