This question came up when we started to look at display name in a CPIM From header of an MSRP SEND (RFC4975): If you put quotes around a display name (called Formal-name in RFC3862), then you do NOT put a space after the end quote and the "<" of the URI.
>From RFC3862<https://tools.ietf.org/html/rfc3862#page-16>, the definition of >From is: From-header = "From" ": " [ Formal-name ] "<" URI ">" ; "From" is case-sensitive In the ABNF the definition of Formal-name is: Formal-name = 1*( Token SP ) / String String = DQUOTE *( Str-char / Escape ) DQUOTE Token = 1*TOKENCHAR So, if the Formal-name starts with double quotes (") there is no space (SP) between the last double quote and the angle brackets in starting the URI. As such, the values should be: Alice <tel:+15145551212> or "Alice"<tel:+15145551212> This is probably a tiny oversight in RFC3862, but I guess we are not going to update the RFC - has anyone come across this before?
