Running this with Saxon:

java com.saxonica.Transform -val schema-aware.xml schema-aware.xsl

First attempt gives the error message

Error at xsl:import-schema on line 9 of file:/c:/temp/schema-aware.xsl:
  Schema at location schema-aware.xsd has target namespace
"http://www.fgeogres.org/dummy"
  but requested namespace was ""

I corrected that by adding a namespace attribute to the import-schema
declaration. The output is now:

A 'list_type' element: 'list'
An 'elem_type' element: 'elem'
An 'elem_type' element: 'elem'
An 'elem_type' element: 'elem'
An 'elem_type' element: 'elem'

which is presumably what you expected.

The XSLT spec actually specifies what it means to omit the namespace
attribute rather indirectly, by reference to the semantics of xs:import in
the schema specification. The schema spec makes it clear that an absent
namespace attribute is a reference to a "no-namespace" schema. By
implication, XSLT inherits the rule for xs:import (in schema part 2 section
4.2.3):

The appropriate case among the following must be true:
3.1 If there is a namespace attribute, then its 7actual value7 must be
identical to the 7actual value7 of the targetNamespace attribute of [the
imported schema].
3.2 If there is no namespace attribute, then [the imported schema] must have
no targetNamespace attribute

I can't account for Altova's behavior - you'll have to ask them.
