This is because you changed your document even more. The issue with your query is that the namespaces you specify in teh query do not fully match the namespaces in your document. If you leave your document unchanged, the following query will work. However, I do not know whether it CREATES the elements in teh correct namesypace becasue I do not know which namespace you intend the elements to be in, so your might have to adapt teh query accordingly:
declare default element namespace "http://www.imsglobal.org/xsd/imscp_v1p1"
declare namespace p2="http://www.imsglobal.org/xsd/imsmd_v1p2"
update insert
