The text layer is designed for people who can't write Javascript --
specifically, it's designed to support the MVS -- map viewer service, at
http://openlayers.org/viewer/ -- it's not designed to be subclassed.

I'm not sure I understand why people would want to use a text layer
rather than something like georss. Are there really that many OpenLayers
users who just use excel and still want to do more fancy things with a
text layer?
