Most of those are already listed in the schema spec eg

      <xs:minInclusive value="-128" id="byte.minInclusive"/>
      <xs:maxInclusive value="127" id="byte.maxInclusive"/>
tells you immediately that the xpath2 for byte is

(:whatever you have for xs:short:) and $value >= -128 and $value <= 127

But he was thinking of a regular expression. Though it seems a bit outrageous to create a regex for a byte, it might look something like this:

regex = "^\s*(([+-]?(1[01]\d|12[0-7]|0?\d?\d))|+?128)\s*$"

Note that this regex does not allow for an empty string (which is correct, as xs:byte('') would fail)
