The WSDL specification should define what it means for two definitions of a
part
of a service description to be equivalent. The notion of equivalence must be
defined
for each definable element, e.g. service, binding, port, etc. For example,
if two
definitions of a portType only differ in the order that the operations are
listed in the
document, then they are equivalent.

This requirement is important since in some usage scenarios a WSDL document
may undergo transformations, e.g. storage and retrieval in a UDDI registry.
These
transformations must result in a transformed document that is equivalent to
the
original document.

The defined notion of equivalence should be used as the basis for digital
signatures
in the sense that two equivalent documents must be assigned the same digital
signature.
