Do not forget to import the haxe.xml.Check class because the rules for the validation check are defined
in there. In this case only an RNode has been applied and the document is checked using the
checkDocument() function. The function is invoked inside a try block because in case of failure an
exception is raised.
All the string comparisons in the Check API are case sensitive; this is particularly important when
defining rules for elements and attributes.
Checking Nodes
The nodes are checked using the enum Rule . Rule has several constructors to cover many possible
validation conditions.

RN ode
The RNode constructor acts on a single node whose element name must match the first argument. The
second optional argument is an array of attribute validation rules. If omitted or empty, the node must
not have attributes to be valid.
