* This list can be modified to add headers * from outside a {@link Message}, this is necessary * since intermediate processing layers often need to * put additional headers. * *
* Following the SOAP convention, the order among headers * are not significant. However, {@link Codec}s are * expected to preserve the order of headers in the input * message as much as possible. * * * *
* To perform SOAP mustUnderstang processing correctly, we need to keep * track of headers that are understood and headers that are not. * This is a collaborative process among {@link Pipe}s, thus it's something * a {@link Pipe} author needs to keep in mind. * *
* Specifically, when a {@link Pipe} sees a header and processes it * (that is, if it did enough computing with the header to claim that * the header is understood), then it should mark the corresponding * header as "understood". For example, when a pipe that handles JAX-WSA * examins the <wsa:To> header, it can claim that it understood the header. * But for example, if a pipe that does the signature verification checks * <wsa:To> for a signature, that would not be considered as "understood". * *
* There are two ways to mark a header as understood: * *
* Intuitively speaking, at the end of the day, if a header is not
* understood but {@link Header#isIgnorable(SOAPVersion, java.util.Set)} is false, a bad thing
* will happen. The actual implementation of the checking is more complicated,
* for that see {@link ClientMUTube}/{@link ServerMUTube}.
