Description

24

Top level element for resource metadata descriptor. The most important things are its attributes. There you can see port type (interface), descriptor name (name) and wsdl location

25 - 29

Property metadata descriptor. This contains metadata information about a specific property. As you can see a property has several attributes :

  • mutability : The property has a constant (constant) value or it could change (mutable);
  • modifiability : Property access mode. Can be "read-only" or "read-write";
  • name : the name of the property. 

30 - 31

ValidValues are used to restrict the set of valid values that a property can assume

32 - 33

StaticValues are used to define a minimum set of values that a property can assume

34 - 35

InitialValues are used to declatively define the set of values that a property will contain when the owner resource is initialized at first time

...

Faults

The only exception that could be thrown in a metadata exchange scenario is when the requestor indicates an unknown dialect.
