>What is the format of the ID in Matlab?

Here is an example:'MATLAB:unrecognizedStringChoice'
In general, the string after the : is suggestive of the error.

This seems like a reasonable idea.

What is the format of the ID in Matlab?  Where is the function name embedded in the ID?

If the function is embedded in the ID, should it also be embedded in the error message itself?

When inputParser throws an exception it includes the error message from the validation function but does not include the identifier.

The offending line in inputParser is:

error ("%s%s", where, msg);


This should support something like:

error (id, "%s%s", where, msg);


where id is set from the validation function exception.

Matlab inputParser DOES work in this way and makes it possible to
do more intelligent up-stream handling of the error.
