∟"long", "int", "short" and "byte" Datatypes

This section describes the built-in primitive datatypes, 'long', 'int', 'short' and 'byte', that represents signed integer numbers for different storage sizes. Leading and trailing whitespaces are allowed and trimmed.

Based on the "integer" datatype, 4 other built-in datatypes are derived in XSD 1.1 to represent signed integer numbers within different storage sizes: "long", "int", "short" and "byte". Their definitions can be summarized as:

The value space of "long" is all signed integer numbers that can be stored in a 64-bit space. "long" values are in the range of -9223372036854775808 and 9223372036854775807.
The value space of "int" is all signed integer numbers that can be stored in a 32-bit space. "int" values are in the range of: -2147483648 and 2147483647.
The value space of "short" is all signed integer numbers that can be stored in a 16-bit space. "short" values are in the range of: -32768 and 32767.
The value space of "byte" is all signed integer numbers that can be stored in a 8-bit space. "byte" values are in the range of: -128 and 127.
Lexical spaces of "long", "int", "short" and "byte" are all possible values in their value spaces represented in decimal format with with leading and trailing whitespaces allowed and trimmed.
Leading zeroes are optional.
Decimal point is not allowed.
"long", "int", "short" and "byte" 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 "long", "int", "short" and "byte" datatypes to declare XML elements:

<?xml version="1.1"?>
<!-- long_int_short_byte_datatype_test.xsd
 - Copyright (c) 2013, HerongYang.com, All Rights Reserved.
-->
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="Long_Int_Short_Byte_Datatype_Test">
  <xs:complexType>
    <xs:sequence>
      <xs:element name="Long" type="xs:long" 
        maxOccurs="unbounded"/>
      <xs:element name="Int" type="xs:int" 
        maxOccurs="unbounded"/>
      <xs:element name="Short" type="xs:short" 
        maxOccurs="unbounded"/>
      <xs:element name="Byte" type="xs:byte" 
        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"?>
<!-- long_int_short_byte_datatype_test.xml
 - Copyright (c) 2013, HerongYang.com, All Rights Reserved.
-->
<Long_Int_Short_Byte_Datatype_Test>
<!-- 2 valid "Long" elements -->
  <Long>   -9223372036854775808  </Long>
  <Long>   09223372036854775807  </Long>

<!-- 2 invalid "Long" elements -->
  <Long>-9223372036854775809</Long>
  <Long> 9223372036854775808</Long>

<!-- 2 valid "Int" elements -->
  <Int>   -2147483648  </Int>
  <Int>   02147483647  </Int>

<!-- 2 invalid "Int" elements -->
  <Int>   -2147483649  </Int>
  <Int>    2147483648  </Int>

<!-- 2 valid "Short" elements -->
  <Short>   -32768  </Short>
  <Short>   032767  </Short>

<!-- 2 invalid "Short" elements -->
  <Short>   -32769  </Short>
  <Short>    32768  </Short>

<!-- 2 valid "Byte" elements -->
  <Byte>   -128  </Byte>
  <Byte>   0127  </Byte>

<!-- 2 invalid "Byte" elements -->
  <Byte>   -129  </Byte>
  <Byte>    128  </Byte>
  
</Long_Int_Short_Byte_Datatype_Test>

When validating this XML document with my XsdSchemaValidator.java program presented earlier in the book, I get 8 groups of errors for 8 invalid XML elements:
