XML Schema miscellaneous data types

XSD miscellaneous data type

This section describes some of the other data types in XML Schema.

Other miscellaneous data types include Boolean, base64Binary, hetegam, floating-point, double-precision, anyURI, anyURI, and NOTATION.

Boolean Data Type

Boolean data is used to specify true or false values.

Here's an example of a logical declaration in a scheme:

The elements in the document should look something like this:

Note: The legal Boolean values are true, false, 1 (true), and 0 (false).

Binary Data Types

Binary data types are used to express data in binary form.

We can use two binary data types:

• Base64Binary (base64 encoded binary data)
• hexBinary (hexcoded binary data)

Here's an example of a hexBinary declaration in a scheme:

AnyURI Data Type

AnyURI data types are used to specify URIs.

Here's an example of anyURI declaration in a scheme:

The elements in the document should look something like this:

Note: If a URI contains spaces, replace them with %20.

Miscellaneous data types

Limiting miscellaneous data types

Qualifications that can be used with miscellaneous data types:

• enumeration (Boolean data types cannot use this constraint)
• Length (Boolean data type cannot use this constraint)
• maxLength (Boolean data type cannot use this constraint)
• minLength (Boolean data type cannot use this constraint)
• pattern
• whiteSpace

Constraint refers to constraint.
