Command: unsetatt <attribute name>

Check the child elements of the current element.
Command: legalchildren

There are commands to set, display and unset the id attributes of elements using the explicit id attribute
access functions.  These commands are provided because they use a different set of routines to the GetAttribute
route using a named attribute (they should give the same result as using a named 'id' attribute of course).
These commands only use the id attribute because it is commn to all elements (except for meta).  Other atributes are
not provided because the test code is slightly cumbersome.

Get the current value of the id attribute (or state if it is unset) for the current element.
Command: getid

Set the current value of the id attribute for the current element.
Command: setid<value>

Unset the id attribute for the current element.
Command: removeid
