""unsignedLong" and "unsignedShort" Datatypes

XSD Tutorials - Herong's Tutorial Examples

∟""unsignedLong" and "unsignedShort" Datatypes

This section describes the built-in primitive datatypes, 'unsignedLong', 'unsignedInt', 'unsignedShort' and 'unsignedByte', that represents unsigned integer numbers for different storage sizes. Leading and trailing whitespaces are allowed and trimmed.

Based on the "nonNegativeInteger" datatype, 4 other built-in datatypes are derived in XSD 1.1 to represent unsigned integer numbers for different storage spaces: "unsignedLong", "unsignedInt", "unsignedShort" and "unsignedByte". Their definitions can be summarized as:

The value space of "unsignedLong" is all unsigned integer numbers that can be stored in a 64-bit storage. "unsignedLong" values are in the range of 0 and 18446744073709551615.
The value space of "unsignedInt" is all unsigned integer numbers that can be stored in a 32-bit storage. "unsignedLong" values are in the range of 0 and 4294967295.
The value space of "unsignedShort" is all unsigned integer numbers that can be stored in a 16-bit storage. "unsignedLong" values are in the range of 0 and 65535.
The value space of "unsignedByte" is all unsigned integer numbers that can be stored in a 8-bit storage. "unsignedLong" values are in the range of 0 and 255.
Lexical spaces of "unsignedLong", "unsignedInt", "unsignedShort" and "unsignedByte" are all possible values in their value spaces represented in decimal format with leading and trailing whitespaces allowed and trimmed.
Leading zeroes are optional.
Decimal point is not allowed.
"unsignedLong", "unsignedInt", "unsignedShort" and "unsignedByte" lexical representations after whitespaces are trimmed should match this regular expression: /[\-+]?[0-9]+/.

To verify these rules, I wrote this simple XSD document that uses "unsignedLong", "unsignedInt", "unsignedShort" and "unsignedByte" datatypes to declare XML elements:

<?xml version="1.1"?>
<!-- unsigedLong_unsignedShort_datatype_test.xsd
 - Copyright (c) 2002-2013 HerongYang.com. All Rights Reserved.
-->
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="UnsignedLong_UnsignedShort_Datatype_Test">
  <xs:complexType>
    <xs:sequence>
      <xs:element name="UnsignedLong" type="xs:unsignedLong"
        maxOccurs="unbounded"/>
      <xs:element name="UnsignedInt" type="xs:unsignedInt"
        maxOccurs="unbounded"/>
      <xs:element name="UnsignedShort" type="xs:unsignedShort"
        maxOccurs="unbounded"/>
      <xs:element name="UnsignedByte" type="xs:unsignedByte"
        maxOccurs="unbounded"/>
    </xs:sequence>
  </xs:complexType>
</xs:element>
</xs:schema>

Here is a sample XML document that can be used to test these declarations:

<?xml version="1.1"?>

  <UnsignedLong>000000000000000000000000000</UnsignedLong>

<!-- 2 invalid "UnsignedLong" elements -->
  <UnsignedLong>18446744073709551616</UnsignedLong>
  <UnsignedLong>-1</UnsignedLong>

<!-- 2 valid "UnsignedInt" elements -->

<!-- 2 invalid "UnsignedShort" elements -->
  <UnsignedShort>65536</UnsignedShort>
  <UnsignedShort>-1</UnsignedShort>

<!-- 2 valid "UnsignedByte" elements -->
  <UnsignedByte>255</UnsignedByte>
  <UnsignedByte>000000000000000000000000000</UnsignedByte>

<!-- 2 invalid "UnsignedByte" elements -->
  <UnsignedByte>256</UnsignedByte>
  <UnsignedByte>-1</UnsignedByte>
</UnsignedLong_UnsignedShort_Datatype_Test>

When validating this XML document with my XsdSchemaValidator.java program presented earlier in the book, I get 6 groups errors for 6 invalid XML elements:
