Hello,
The ABNF grammar for Alert-Info is:
Alert-Info = "Alert-Info" HCOLON alert-param *(COMMA alert-param)
alert-param = LAQUOT absoluteURI RAQUOT *( SEMI generic-param )
I have an application that seems to utilise just a generic-param without
a URI. However, I don't see any */? quantifiers for absoluteURI which
suggest that it's optional:
absoluteURI = scheme ":" ( hier-part / opaque-part )
Maybe it's a failure on my part to properly understand ABNF, however.
My fundamental question is: is there any grammatically acceptable way to
have an Alert-Info header value consisting of no URI and just a
generic-param, e.g.
Alert-Info: ;internal=xyz
Alert-Info: <>;internal=xyz
Thanks!
