The optional Category field is a short identifier that classifies the

kind of message when an analysis produces several kinds of diagnostic.
|

|

Many analyses want to associate diagnostics with a severity level.
|

Because Diagnostic does not have a severity level field, an Analyzer's
|

diagnostics effectively all have the same severity level. To separate which
|

diagnostics are high severity and which are low severity, expose multiple

Analyzers instead. Analyzers should also be separated when their

diagnostics belong in different groups, or could be tagged differently
|

before being shown to the end user. Analyzers should document their severity
|
||||
level to help downstream tools surface diagnostics properly.
|
||||
|
||||
Most Analyzers inspect typed Go syntax trees, but a few, such as asmdecl

and buildtag, inspect the raw text of Go source files or even non-Go
