SD Declarations and PortTypes
OGSI models portType inheritance using gwsdl:portType
Modeled like W3C proposal for interface inheritance
GGF commits to moving to WSDL 1.2 when W3C is finished
SDs are inherited down a gwsdl:portType inheritance
hierarchy
Overloading is handled like operations
SDEs are namespace qualified
Duplicate SDEs are elided
Values can be associated with (certain) SD Declarations
Only SDEs where mutability=“static”
These are like “class constants”
Values are aggregated down a portType inheritance hierarchy
