<!--

The following entity declarations enable external/flexible content in
the Signature content model.

#PCDATA emulates schema string; when combined with element types it
emulates schema's mixed content type.

%foo.ANY permits the user to include their own element types from
other namespaces, for example:
 <!ENTITY % KeyValue.ANY '| ecds:ECDSAKeyValue'>
 ...
 <!ELEMENT ecds:ECDSAKeyValue (#PCDATA)  >
