[Xml-compile] "inheriting" toXML ?

[E R]

Stepping back one question...

Can I change the representation of the 'xsd:dateTime' type via addTypemaps()?

(Here 'xsd:' is  xmlns:xsd="http://www.w3.org/2001/XMLSchema" )

In my above example, I can get rid of the error message by adding:

    sub toXML { die "here" }

to the mydate package. toXML() never gets called, but now I get a new error:

error: complex or simpleType dateTime for typemap unknown

I get a similar error if I use:

    $schema->addTypemap('xsd:datetime' => 'mydate');
