| This interface represents methods for manipulating OptionTags
values for any header that contains an OptionTag value. Option tags are
unique identifiers used to designate new options (extensions) in SIP. Note
that these options appear as parameters in those header fields in an
option-tag = token form. Option tags are defined in standards track RFCs.
This is a change from past practice, and is instituted to ensure continuing
multi-vendor interoperability.
