it would be great to have text labels on vector features!

This is one way to do it, but defining text labels as style property
instead of a layer property would be a better way, if labelling should
later be defined by StyledLayerDescriptor (SLD). So instead of using
you should use
The name "textSymbolizerProperty" instead of "textAttrToDisplay" would
be more conform to the SLD specification.
As a next step, the font and placement of the label could also be
defined using style properties. Again, a look at the TextSymbolizer in
the SLD specification  will give you an idea.
