The "X-3GPP-Authorization-Flags" header is used optionally by the AP to indicate an authorization flag or a list of authorization flags from the application specific user security setting (USS) to the AS. It contains a list of authorization flags separated by comma (,) and each authorization flag is surrounded by quotation marks (").

Table G.4: Syntax of X-3GPP-Authorization-Flags extension-header

X-3GPP-Authorization-Flags = "X-3GPP-Authorization-Flags" ":" auth-flag-list

auth-flag-list = DQUOTE auth-flag DQUOTE *("," DQUOTE auth-flag DQUOTE)

auth-flag = *(%x20-21 / %x23-7E)

In the syntax definition the rule ‘auth-flag’ refers to the authorization flag and it is defined as a string of printable characters and spaces but excluding quotation marks. The exact type definition for authorization flag is done in 3GPP TS 29.109 [3] as part of the User Security Setting definition.
