The Alternate dictionary contains classes that
describe sets of data values which are interchangeable with each
other.
The Alternate_Values describes a direct
one-to-one relationship of arrays of data values. Each data
array must have the same dimensionality and number of
elements.
The Data_Values class describes the values
stored in a data array.
The Local_Internal_Reference class is used to
cross-reference other classes or objects within the
product.
This section contains the simpleTypes that provide more constraints
than those at the base data type level. The simpleTypes defined here build on the base data
types. This is another component of the common dictionary and therefore falls within the
pds namespace.
The local_reference_type attribute provides the
name of an association between an entity identified by a
local_identifier_reference and another corresponding entity
identified by a local_identifier
