Okay, trying to keep this to a discussion of technique, I would have envisioned a loosely coupled architecture being adopted intra--organization that allowed anyone to generate a DTD/schema with only the need to agree on terms. The DTD/schema repository is available to all to define source/definition formats for mapping any document. They don't have to be one "standard." They don't have to be a standard at all as long as there is a DTD or schema in the repository.
Each application is responsible for its own data format and any it chooses to publish. Using middleware, even traditional EDI tools, would provide a mechanism for mapping from any format to any other format as needed by each application. If, for instance, inbound X12 data is needed by several applications the EDI tool can either map to a published format all systems can use or map to separate formats according to individual application DTD/schemas. Mercator can do this in a one operation. Gentran would need to use multiple processes and maps (yet to see how Unix Server 6.0 handles many to many mapping.)
What am I missing?

The only thing special to me about "X12 to XML1 to XML2" to me is an
ability to convert from one internal corporate data standard to another
using XSLT. If we were dealing with one accepted XML standard only, then
multiple mappings are not required. However, we know it is not true in
reality.
Once I implement a conversion "X12 to myXML" I can publish it and let you
implement "myXML to yourXML" by using XSLT.
Advantages of this approach:
1. Conformance to established standards,
2. Reduction of data traffic (some clients may need only limited subset of
XML data),
3. Documenting & reporting.
