Set the fragment for this URI. A non-null value is valid only
if this is a URI conforming to the generic URI syntax and
the path value is not null.

@param p_fragment the fragment for this URI

@exception MalformedURIException if p_fragment is not null and this
URI does not conform to the generic
URI syntax or if the path is null
