Looks good to me overall. @angelozerr , let me know if it's fine with you.

@AlexXuChen it should be nice to have 2 tests with your PR:

• test which rename ns
• test which rename local name

These tests exist in https://github.com/eclipse/lemminx/blob/master/org.eclipse.lemminx/src/test/java/org/eclipse/lemminx/services/XMLRenameTest.java, although not explicitly called ns:..., however the behaviour is the same. I made the bug fix such that no tests would break.

The main idea is to copy/paste a test with ns rename and change the newText with ns:BBB instead of BBB and do the same thing for local name rename.

It works like a charm, good job @AlexXuChen !
