I believe Xerces is right.
According to schema specs if there is a namespace attribute is present,
then its value must be identical to the value of the targetNamespace
attribute of imported schema. 
If there is no namespace attribute, then imported Schema must have no
targetNamespace attribute.
In your shoppingcartline.xsd you have *targetNamespace* attribute, thus
then importing it you should specify *namespace* attribute on import.

See 6.2.3  (Schema Part 1):
"The normalized value of its namespace [attribute] indicates that the
containing schema document may contain qualified references to schema
components in that namespace (via one or more prefixes declared with
namespace declarations in the normal way). If that attribute is absent,
then the import allows unqualified reference to components with no
target namespace."
