I guess it depends on your definition of the word "application". Is it
really the case that XML editors and XML databases are not "applications"
because they choose to preserve details that most XML consumers would
consider irrelevant?

I consider it a limitation of the infoset that it supports some types of
applications and not others. It may still be rectified. The spec. already
has a concept of optional information items so I would expect (e.g.) CDATA
and unknown entity reference to fall into that category.

also a gigantic undertaking in the foundations of knowledge.
