Feature syntax string values

All,

It has been pointed out that the syntax did not provide any mechanism for
allowing quotes within a quoted string.  I have modified the draft to allow
'\'-escaping for any character (specifically '\' and '"') within a string
value.

Revised syntax productions are:

  string     =  DQUOTE *( str-char / esc-pair ) DQUOTE
                ; quoted string of SP and VCHAR without DQUOTE
  str-char   =  ( %x20-21 / %x23-5B / %x5D-7E )
                ; any of SP or VCHAR without DQUOTE or '\'
  esc-pair   =  "\" any-char
  any-char   =  ( SP / VCHAR )

This is the only last-call change (so far) that is not simply an editorial
clarification.
