Descripción de capas con nombre asignado

Descripción

This operation takes a list of layers as input in the request and returns the description of those layers, including tables, label sources (named or inline), attributes, themes, and visibility constraints. The layer portions of the response from this describe can be incorporated in a map definition, which can then be used in a REST Render Map or Render Map Legend request.
