XTCE13 — needs to be updated for items that no longer support hex, octal, binary

Items that previously were typed as FixedIntegerValueType but were changed to become long need to be revisited to update the documentation annotation. For instance IntegerDataType initialValue attribute documentation:
"Default/Initial value is always given in calibrated form. Default is base 10 form; binary, octal, or hexadecimal values may be given by preceding value with 0[b|B], 0[o|O|, 0[x|X] respectively."
Such forms no longer validate against the schema.
