<p class="MsoNormal">So the value I need is “Schema:Trees” but I
don’t
want to hardcode this value. I can access the Class Name if I get it
from a layer,
but I’m trying to add a LayerDefinition to the repository, and I don’t
have a layer to reference yet. It looks like SchemaName:ClassName. Any
suggests?<o:p></o:p></p>
