Issue with seemingly different XML-DSig schemas

["Huehnlein, Detlef" <Detlef.Huehnlein@secunet.com>]

Dear DSS-X-Team,

for some (most likely W3C-internal) reason there are two bitwise identical XML-DSig schemas
out there (at #1 http://www.w3.org/TR/xmldsig-core/xmldsig-core-schema.xsd  and 
#2 http://www.w3.org/TR/2002/REC-xmldsig-core-20020212/xmldsig-core-schema.xsd ),
different standards use #1 (e.g. DSS-Core, SAML 1.1) or #2 (e.g. XML-Enc, SAML 2.0, XAdES etc. seemingly
all standards, which use XML-Enc) and many tools (editors, code generators etc.) do not recognize that they are 
in fact equal and produce according errors (double definition of elements).

Do we see any chance to harmonize those two "worlds" in order to avoid the nasty
manual tweaking of schema documents if one wants to use schemas from world#1 and world#2? 

This problem should in particular occur if one wants to build software, which supports
both the DSS Core http://docs.oasis-open.org/dss/v1.0/oasis-dss-core-schema-v1.0-os.xsd 
and the AdES Profile http://docs.oasis-open.org/dss/v1.0/oasis-dss-profiles-AdES-schema-v1.0-os.xsd,
which in turn includes http://uri.etsi.org/01903/v1.3.2/XAdES.xsd . 

... Or can we expect that the tools become smart enough to handle this situation
properly?

BR,
 Detlef
