Hi Michael, thanks for your response. I don't quite sure i've understood you
correctly. If points 1 and 2 are questions, then answers are:
1) i suppose the point 1 is regarding the error.xml instance. I don't see any
reason to use schemaLocation specified on the xs:import. From my point of view
xs:import is an incapsulated part of the schema and i only should provide valid
schemaLocations either by external-schemaLocation property, either by
xsi:schemaLocation hint. I hope you agree the xsi:schemaLocation in error.xml
is absolutely valid and enough for validation. If you suppose i need to use
schemaLocation specified on the xs:import, please explain this.
2) i think the point is inside - out, should be : "Using the URI specified in
the instance as a schemaLocation in the xs:import" and if i understood right,
this behaviour is just wrong. if i have a set of schemas under the same
namespace whose linked relatively, this behaviour will break everything. In a
case of honour-all-schemalocations this behaviour even more questionable.

whish resolves relatively, it will break everything.
