The implementation of validation of indicator class.
Some data can become indicator class if they are validated as member of this indicator class. Basic validation is done through the restriction element, however for more complex validation you can use the functional validation.
The summary description of the validation.
Fill in the short and self-explanatory summary of the validation procedure.
Unspecified comment - other relevant information.
Enter important objective information about the validation procedure if necessary for the understanding. Do not enter your personal comments (use the REVIEW entity instead).
The description the data allowed on the validation input
Input data for the validation - you may reference them.
Fill in if there are any known limits limiting the use of this validation.
For example if the validation can not recognize some type, enter it here.
The name of the validation as it is displayed in the lists (may be abbreviated).
When the computer is manipulating with the name of the validation (creating lists, references etc.) it uses this piece of metadata.
The URN of the validation or interpret (so that it could be found via the registry).
Enter the URN of the validation or interpreter. If this validation is implemented as standalone webservice (any you do not want it to be accessed via registry), use the Validation URL metadata piece.
The URL of the validation or interpreter (in the case it is not accessible through the registry).
If this service is accessible only through the registry, use the Validation URN metadata piece instead.
The source code for validation defined in LUA language.
For clues how to write the LUA functions, see the examples.
The source code for the simple validation method called Number/Unit (validates number with known unit).
For simple validation recipe for body height, see example.
The author (or authors) of validation
You may enter multiple authors.
