The '''src''' and '''trait''' traits are always provided together (except for the special case of the [[Include Element]]).  They are used only in empty Operator elements, to specify the "contents" of the operator:

The '''src''' trait can refer to any ''menu'' element by it's name, or can use one of the "relative" sources:

*'''Me()''' - refers to the object element whose property the operator element is modifying.

*'''Parent()''' - refers to the parent of Me(), the object element of which Me() is a child.

*'''Sibling(''SiblingName'')''' - refers to one of the siblings of Me() - that is, the object elements that are also children of Parent().  The name of the sibling must be provided as an argument - this is why no two siblings should have the same name trait.

*'''Child(''ChildName'')''' - refers to one of the object elements that are children of Me().  Again, the name must be specified.

The '''trait''' trait can refer to any ''property'' of the source element.  The current value of this property is used as the "contents", or second operand, of the operator.
