Restriction totalDigits

Hi to all,
    I'm having problems with restriction totalDigits to type decimal.
<xsd:restriction base="xsd:decimal">
  <xsd:totalDigits value="13" />
  <xsd:fractionDigits value="3" />
</xsd:restriction>

By this restriction the minor valid number is 99999999999999.0 because the
code generate by axis. On totalDigits restriction I understand that is
valid any number between 0 and 10^13. Am I right? Or this restriction is to
numbers bigger than 99999999999999.0 ?

Thanks,
