Data Structure Validation: Error message to long and hard to read

[CFuerstenau]

• shorten title/error to 200 chars
• remove title from list
• move the number of errors to end
• add instruction on what to do on top

What is your improvement proposal all about?

in BExIS we have a very long constrain. This constrain should not be fully shown in the error, when validating the data

How does the current implementation works and what is wrong about it?

many lines of constrain is shown and the important error message can't hardly befound

How should the (part of the) feature be implemented?

just show part of the constrain
is it possible to add an advise how to handel the error. this would be also nice for other errors as the error messsages are often hard to interpret
