/*
Conceptually, the agnostic EndpointAddress class represents all of UNION(v200408,v10) data thusly:
- Address Uri (both versions - the Address)
- AddressHeaderCollection (both versions - RefProp&RefParam both project into here)
- PSP blob (200408 - this is PortType, ServiceName, Policy, it is not surfaced in OM)
- metadata (both versions, but weird semantics in 200408)
- identity (both versions, this is the one 'extension' that we know about)
- extensions (both versions, the "any*" stuff at the end)
When reading from 200408:
- Address is projected into Uri
- both RefProps and RefParams are projected into AddressHeaderCollection,
they (internally) remember 'which kind' they are
- PortType, ServiceName, Policy are projected into the (internal) PSP blob
- if we see a wsx:metadata element next, we project that element and that element only into the metadata reader
- we read the rest, recognizing and fishing out identity if there, projecting rest to extensions reader
When reading from 10:
- Address is projected into Uri
- RefParams are projected into AddressHeaderCollection; they (internally) remember 'which kind' they are
- nothing is projected into the (internal) PSP blob (it's empty)
- if there's a wsa10:metadata element, everything inside it projects into metadatareader
- we read the rest, recognizing and fishing out identity if there, projecting rest to extensions reader
When writing to 200408:
- Uri is written as Address
- AddressHeaderCollection is written as RefProps & RefParams, based on what they internally remember selves to be
- PSP blob is written out verbatim (will have: PortType?, ServiceName?, Policy?)
- metadata reader is written out verbatim
- identity is written out as extension
- extension reader is written out verbatim
When writing to 10:
- Uri is written as Address
- AddressHeaderCollection is all written as RefParams, regardless of what they internally remember selves to be
- PSP blob is ignored
- if metadata reader is non-empty, we write its value out verbatim inside a wsa10:metadata element
- identity is written out as extension
- extension reader is written out verbatim
EndpointAddressBuilder:
- you can set metadata to any value you like; we don't (cannot) validate because 10 allows anything
- you can set any extensions you like
Known Weirdnesses:
- PSP blob does not surface in OM - it can only roundtrip 200408wire->OM->200408wire
- RefProperty distinction does not surface in OM - it can only roundtrip 200408wire->OM->200408wire
- regardless of what metadata in reader, when you roundtrip OM->200408wire->OM, only wsx:metadata
as first element after PSP will stay in metadata, anything else gets dumped in extensions
- PSP blob is lost when doing OM->10wire->OM
- RefProps turn into RefParams when doing OM->10wire->OM
- Identity is always shuffled to front of extensions when doing anyWire->OM->anyWire
