However, translating these to the front end (e.g. for non-English) can be tricky as it results in trial and error, or scraping the code.

Goals:

• Using unique IDs for the errors will give translator a reliable identifier for translating.
• It should be possible to use code to prevent an ID from being reused
• It should be possible to procedurally generate a list of errors
