XML Schema Built-In Types

Type	Example	Description
string	This is a string.	A sequence of legal XML 1 characters.
normalizedString	This is a normalized string.	A sequence of legal XML 1 characters that does not contain carriage returns, line feeds, or tabs.
token	Token1 Token2 Token3	A tokenized string of legal XML 1 characters that does not contain carriage returns, line feeds, or tabs.
byte	-128	A numeric value from -128 through 127.
unsignedByte	255	A numeric value from 0 through 255.
base64Binary	6e7P	Base64-encoded binary data. Base64 encoding is described in RFC 2045.
hexBinary	B2AF	Hex-encoded binary data. Each binary octet is encoded into its two-character hexadecimal equivalent. The example has a binary representation of 1011001010101111.
integer	123456789	A numeric value meeting the mathematical definition of an integer. Basically, an infinitely bounded number that can be positive or negative.
positiveInteger	123456789	A numeric value that meets the mathematical definition of a positive integer. Basically, an infinitely bounded positive number, not including zero.
negativeInteger	-123456789	A numeric value that meets the mathematical definition of a negative integer. Basically, an infinitely bounded negative number, not including zero.
nonNegativeInteger	123456789	A numeric value that meets the mathematical definition of a non-negative integer. Basically, an infinitely bounded positive number, including zero.
nonPositiveInteger	-123456789	A numeric value that meets the mathematical definition of a nonpositive integer. Basically, an infinitely bounded negative number, including zero.
int	-2147483648	A numeric value from -2147483648 through 2147483647.
unsignedInt	4294967295	A numeric value from 0 through 4294967295.
