Overview

Base class for XML Signature transforms.

Each transform declares input and output types (:octets or :nodeset) plus an identifier URI. The reference resolver chains them with default type conversion when types mismatch (octets → nodeset via XML parse; nodeset → octets via inclusive C14N 1.0).
