Miscellaneous Types

The miscellaneous types group contains three primitive types: base64Binary, boolean, and hexBinary. Figure A-5 shows the relationship among these types in the XSD types hierarchy.

Figure A-5: The remaining three XSD built-in types are all primitive types.

base64Binary

The base64Binary type represents the set of all Base64-encoded data of up to infinite length where the entire binary stream must be encoded with Base64 Content-Transfer- Encoding as defined in Section 6.8 of RFC 2045. It lexically covers the set of all finite- length sequences of binary octets.

Base Type	Derived Type	SQL Server Type	.NET Type
anySimpleType	N/A	BINARY, VARBINARY, or IMAGE	System.Byte[]
Applicable Facets	enumeration, length, maxLength, minLength, pattern, whiteSpace
Example	<b64>0Ae5FTIw</b64>

boolean

The boolean type represents the set of values 1, 0, true, and false.

Base Type	Derived Type	SQL Server Type	.NET Type
anySimpleType	N/A	BIT	System.Boolean
Applicable Facets	pattern, whiteSpace
Example	<bool>true</bool>

hexBinary

The hexBinary type represents the set of all hex-encoded data of up to infinite length. It lexically covers the set of all finite-length sequences of binary octets. Note that uppercase is preferred when using the hex digits A to F.

Base Type	Derived Type	SQL Server Type	.NET Type
anySimpleType	N/A	BINARY, VARBINARY, or IMAGE	System.Byte[]
Applicable Facets	enumeration, length, maxLength, minLength, pattern, whiteSpace
Example	<hex>0A2CF9</hex>
