XSD Simple Types

---

The translation of XSD simple types into ASN.1 types is straightforward; in most cases, a one-to-one mapping from XSD simple type to ASN.1 primitive type exists. The following table summarizes these mappings:

XSD Simple Type	ASN.1 Type
anyURI	UTF8String
base64Binary	OCTET STRING
boolean	BOOLEAN
byte	INTEGER (-128..127)
date	UTF8String
dateTime	UTF8String
decimal	UTF8String
double	REAL
duration	UTF8String
ENTITIES	SEQUENCE OF UTF8String
ENTITY	UTF8String
float	REAL
gDay	UTF8String
gMonth	UTF8String
gMonthDay	UTF8String
gYear	UTF8String
gYearMonth	UTF8String
hexBinary	OCTET STRING
ID	UTF8String
IDREF	UTF8String
IDREFS	SEQUENCE OF UTF8String
integer	INTEGER
int	INTEGER (-2147483648..2147483647)
language	UTF8String
long	INTEGER (-9223372036854775808..9223372036854775807)
Name	UTF8String
NCName	UTF8String
negativeInteger	INTEGER (MIN..-1)
NMTOKEN	UTF8String
NMTOKENS	SEQUENCE OF UTF8String
nonNegativeInteger	INTEGER (0..MAX)
nonPositiveInteger	INTEGER (MIN..0)
normalizedString	UTF8String
positiveInteger	INTEGER (1..MAX)
short	INTEGER (-32768..32767)
string	UTF8String
time	UTF8String
token	UTF8String
unsignedByte	INTEGER (0..255)
unsignedShort	INTEGER (0..65535)
unsignedInt	INTEGER (0..4294967295)
unsignedLong	INTEGER (0..18446744073709551615)

The C/C++ mappings for these types can be found in the section above on ASN.1 type mappings.
