Each element in the XML document may have a mode="" attribute that gives a mode expression. If there is no mode attribute or it is empty or the mode expression matches the list of modes, then the element is accepted. Otherwise it and all of its children are cut from the document.The mode expression is a boolean expression using the operators & (which unfortunately must be escaped as "&"), |, , to build mode matching expressions from a list Parentheses may be used to group operations. of words. , and are synonyms.! may be used as a prefix negation operator, so !a means "unless mode a".Examples: Modes mode="..."
