For developpers:
You can use XML-schema that defines structure of gadget if you want.
Just replace <Module> in your gadget with <Module xmlns="http://dzonny.cz/google/HPgadget" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://dzonny.cz/google/HPgadget http://dzonny.cz/google/HPgadget.xsd">.
Remember to comment it out (leave only <Module> before publishing!!!
