Calling WSE filters directly

dotnet web services enhancements:

I would like to make use of WSE filters directly bypassing standard pipeline
processing mechanizm.
In other words I have a payload in a form of raw XML and would like to apply
some filters' processig power onto it.

I tried this:

// 1.create SoapEnvelope
SoapEnvelope se = new SoapEnvelope();

se.LoadXml(xmlEnvelope); // xmlEnvelope is a text string with "standard"
soap payload

// 2.specify X509 security token for the Context of SoapEnvelope
X509SecurityToken token = GetClientToken();

se.Context.Security.Tokens.Add( token );

se.Context.Security.Elements.Add( new MessageSignature( token ) );

// 3.create a new pipeline with Security filter
Pipeline pipeline = new Pipeline();

pipeline.OutputFilters.Clear();

pipeline.OutputFilters.Add(new SecurityOutputFilter());

// 4. Process message (apply signature)
pipeline.ProcessOutputMessage( se );

xmlEnvelope = se.OuterXml; // this is my new "signed" XML

================

It all works fine, but I am curious about 2 things:

1. If I do not create a pipeline, but just call
new SecurityOutputFilter().ProcessMessage(se);

It does not work, meaning xmlEnvelope = se.OuterXml; returns original
"unsigned" XML

2. If I want to apply one more signature on top of existing I can not do it,
because my message already has wsa:MessageID and second processing will not
work.

SO.... the question: HOW TO MAKE USE OF WSE FILTERS' SERVICES (HOW TO CALL
THEM DIRECTLY IN THE ORDER I CHOOSE)

Thank toy,

Andrew

Why use WSE at all? Why not create your own pipeline and setup the pipeline
in any order you choose?
