/**
* Description and storage of {@linkplain org.opengis.parameter.ParameterValue parameter values}.
* The first two paragraphs below are adapted from OpenGIS® Spatial Referencing
* by Coordinates (Topic 2) specification.
*
* Most {@linkplain org.opengis.parameter.ParameterValue parameter values} are
* numeric, but for some operation methods, notably those implementing a grid interpolation
* algorithm, the parameter value could be a file name and location (this may be a URI). An example
* is the coordinate transformation from NAD 27 to NAD 83 in the USA; depending on the
* locations of the points to be transformed, one of a series of grid files should be used.
*
*
Some operation methods may require a large number of coordinate operation
* parameters. Also, some operation methods require that groups of parameters be repeatable as a
* group. In such cases, it is helpful to group related parameters in {@linkplain
* org.opengis.parameter.ParameterDescriptorGroup parameter groups}. Two or more parameter groups
* are then associated with a particular operation method, and each parameter group consists of a
* set of {@linkplain org.opengis.parameter.ParameterDescriptor operation parameters}, or other,
* nested parameter groups. This way of modelling is not mandatory; all coordinate operation
* parameters may be assigned directly to the coordinate operation method.
