In fact, things have caught on under the hood here and there, without making
much fuss. For instance Cocoon has cXML and Perl has XML::Filter::Cache both of
which store a simple list of SAX events in order to simulate a parse, only
faster. In the wild, you will find a variety of more or less ad hoc solutions to
the same problem.
What is true however is that no interoperable solution has been devised yet.
