Deletes a service attribute with the specified name attached to the specified element. (See also below: What are Service Attributes?)

Parameters:

element

The element whose service attribute is to be deleted. If not specified, the generator context element is assumed by default, which is the same as the call: removeServiceAttr(contextElement, attrName)
attrName
The name of the service attribute to be deleted.
Returns:
The value of the deleted service attribute or null, if no service attribute with the specified name has been attached to the specified element.

Note: null can be also a legitimate value of a service attribute. To distinguish if the attribute had a null value or did not exist, use hasServiceAttr() function.
