// Notes regarding the ownership model between the nsSOAPEncoding (encoding)

// and the nsSOAPEncodingRegsitry (registry). To avoid cyclic referencing
53
// and thereby leaking encodings and the registry holding them the registry
54
// was given ownership of the encodings. In the encoding specialized
55
// AddRef() and Release() functions were written to pass the refcounting
56
// to the registry. Instead of ref couting the encodings all refs are
57
// accumulated in the registry. When the registry is the only thing holding
58
// on to the encodings it's own refcount will hit zero causing it to
59
// go away and take with it any encodings stored in its hashtable. To make
60
// this work the registry had to be a weak reference (*-style pointer)
61
// in each encoding and the storage of the encodings had to be weak as
62
// well (*-style pointers in the nsObjectHashtable).
