Description
It's possible to set a security Provider to use with Signature via the JSR-105 API, by setting the "org.jcp.xml.dsig.internal.dom.SignatureProvider" property to the Provider in the DOMSignContext.setProperty method (ref: https://issues.apache.org/jira/browse/SANTUARIO-509).
This task is to add support to WSSEcSignature, and SignatureProcessor to set this property if a security provider is specified. A new method "setSignatureProvider" is added to WSSecSignature if working directly with the API. On the receiving side, it can be set via RequestData.setSignatureProvider().
