IPP> Revised ABNF per Monday's Phone Conference

[Bergman, Ron]

Here is my proposed ABNF to document the agreed restrictions in yesterday's
phone call.  I may be missing some of the class names but this should
correctly linl\k each class to only one set of units.


media-size-self-describing-name = 
          ( class1 "_" size-name "_" short-dim "-" long-dim "in" ) |
          ( class2 "_" size-name "_" short-dim "-" long-dim "mm" )

   class1 = "na" | "asme" | "oe" 

   class2 = "iso" | "jis" | "jpn" | "prc" | "roc" | "om"

   size-name = ( lowalpha | digit ) *( lowalpha | digit | "-" )

   short-dim = dim

   long-dim = dim

   dim = integer-part [fraction-part] | "0" fraction-part

   integer-part = non-zero-digit *digit

   fraction-part = "." *digit non-zero-digit

   lowalpha = "a" | "b" | "c" | "d" | "e" | "f" | "g" | "h" | "i" |
              "j" | "k" | "l" | "m" | "n" | "o" | "p" | "q" | "r" |
              "s" | "t" | "u" | "v" | "w" | "x" | "y" | "z"

   non-zero-digit = "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9"

   digit    = "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9"


Any comments?
