WS-SecurityPolicy 1.2

[Lijun Liao <lijun.liao@rub.de>]

There may be some bugs in the example between lines 3177 and 3283:

1. If we process wsse:Security from the first child element to the last
one, then we cannot validate the reference that refers to "Header2" in
sig1, since till now it is still invisible (encrypted).
2. If we process wsse:Security from the last child element to the first
one, then we cannot verify the signature sig1, since till now it is
still invisible (encrypted).
