That is *your* problem, not the processor's problem. You added the namespace node to the result on the document element of the result ... what if 100 levels deep, 10 megabytes away from the start tag of the document element, you needed that namespace node to be in scope?
Shouldn't the processor be more intelligent to avoid generating any namespace declarations which are used nowhere in the output?
By what criteria could that decision possibly be made?
Probably this could be a minor enhancement request for Saxon :)
I agree with Colin: enhancements shouldn't break conformance.

Because the specification requires all attached namespace nodes to be copied to the result tree. Since you didn't prune the namespace node for XSD, it is still attached to the literal result element, so it must be copied.
And the specification cannot imply its removal or be changed to wait for your test of use: the result tree can be instantaneously serialized, which would include any attached namespace nodes. As soon as an element's content is begun, that element's start tag is allowed to be serialized to the output without keeping it around. Remember the result tree cannot be inspected. This allows an application not to keep the result tree in memory before serialization. Your "enhancement" would break so many aspects of implementation.
I hope this helps.
