The XMLElement(s, attrList, children) command is the primary constructor used to create XML elements in Maple.

The first argument s is always the name of the element that is created. If no further arguments are included in the calling sequence, then an empty XML element is constructed and returned.

The attrList parameter represents the attributes of the newly constructed element.

If the third argument children is also a list, then it is taken to be a list of all the child elements to place inside the newly formed element returned by the XMLElement constructor.

If the arguments after the second argument are not of type list, they are interpreted as being child elements of the tree node.

If the second argument is not of type list, then all arguments after the first argument are taken to be children of the tree node that is constructed.
