Summary

Update the XML Signature implementation (in the java.xml.crypto module) in the JDK to version 3.0.5 of Apache Santuario with 4 new SHA-3 based Elliptic Curve XML signature methods.

Problem

Apache Santuario 3.0.5 introduced 4 new Elliptic Curve signature methods. We should support them and add their URIs as static final strings in the SignatureMethod class.

Solution

Import Apache Santuario 3.0.5.
