"grammar" dfn-type

[dontcallmedom]

The definition contract defines grammar to be used as a type

just for definitions of operators used in grammar definitions

The Web App Sec Working Group has been using it with a different meaning; in most of these cases, they are actual names of the token in a grammar (rather than operators):

• cache
• cookies
• storage
• executionContexts
• *
• optional-ascii-whitespace
• required-ascii-whitespace
• serialized-policy
• serialized-policy-list
• serialized-directive
• directive-name
• directive-value
• serialized-source-list
• 'none'
• source-expression
• scheme-source
• host-source
• scheme-part
• host-part
• host-char
• port-part
• path-part
• keyword-source
• 'self'
• 'unsafe-inline'
• 'unsafe-eval'
• 'strict-dynamic'
• 'unsafe-hashes'
• 'report-sample'
• 'unsafe-allow-redirects'
• nonce-source
• base64-value
• hash-source
• hash-algorithm
• ancestor-source-list
• ancestor-source
• policy-token
• extension-token
• integrity-metadata
• hash-with-options
• option-expression
• hash-algo
• base64-value
• hash-expression

Probably some relationship to #6
