 The list of errors at the top of the file should remain in numerical order, so it's easy for readers to scan. Each impacted error code should now have a link to the anchor tag for the new section. Repeat the list in the new section, but without the anchors, as shown in the highlighted text.

+Rework the highlighted section so the focus is on how to correct each error. This article doesn't need to explain the associated language feature. Instead, in each section, provide links to language reference or language specification material that explains the rules violated when these diagnostics appear. Add explanatory context after each correction (in parentheses with the error code). Provided brief reasons why each correction is needed. Use detailed, sentence-style explanations rather than brief imperative statements. For each recommendation put the affectived error codes in parentheses, and in **bold** style. Remove extensive examples.
