Several events include useful context information that can be accessed
from XPath expressions using the `event()` function.  I would like to be
able to add context information to events that are dispatched using the
`xf:dispatch` element[0].  I invision this functionality being used in
something like the following way (assuming that the `xf` prefix maps to
the XForms namespace and the `ev` prefix maps to the XML Events
namespace):

  <xf:model id="m">
    <xf:action ev:event="foo">
      <xf:message ev:event="foo"
        >Hello, <xf:output value="event('name')"/></xf:message>
      <xf:setvalue ref="event('context')/name" value="event('name')"/>
    </xf:action>
  </xf:model>

  <!-- ... -->

  <xf:dispatch name="foo" target="m">
    <xf:property name="context" value="instance('other')/context"/>
    <xf:property name="name" value="@name"/>
  </xf:dispatch>
