\title{ Example XML Event Parser Handler Functions}
\description{
A closure containing simple functions for the different
types of events potentially called by the \link{xmlEventParse},
and some tag-specific functions to illustrate how one can
add functions for specific DTDs and XML element types.
Contains a local \link{list} which can be mutated
by invocations of the closure's function.
}
\usage{
xmlHandler()
}
\value{
List containing the functions enumerated
in the closure definition along with the
\link{list}.
