IMHO the best thing to do would be to declare the field as static text in
the studio, and have your class MyHref extend CSpStaticText.
This is what Grace and I are doing in a current project for several hrefs
that depart from the ND pointy-clicky mode.
The key concept is to override the init method, and to add a listener for
the onBeforeHtmlOutputEvent. This uses java's anonymous inner class feature.
