Thanks very much for your response.
How can I use "instance of" with Basex? I can not do: $a instance of Action. Action an abstract ComplexType.
Thanks

Hi An,
the root function returns the root of the tree to which the current node belongs, usually be a document node. You can retrieve the attribute according to your root element e.g. by $otx/ROOT_ELEMENT/@package, where ROOT_ELEMENT ist the root element of your document.

Hi,
In my xquery, I use the root() function to return the root element of an element. I could get the root element,  but I couldn't get any attributes of it.
For example: 
   		for $value in collection()/otx/imports/import
   		let $otx:=root($value)	                        		
   		return $otx/@package
Thanks
Cheers,
An
