15.2.22. XSD Miscellaneous data types

Boolean data type (Boolean Data Type) ¶

Boolean data properties are used to specify true or false values.

Here is an example of a logical declaration in a scheme:

<xs:attribute name="disabled" type="xs:boolean"/>

The elements in the document should look like this:

<prize disabled="true">999</prize>

注意： Legal Boolean values are true, false, 1 (for true), and 0 (for false).

Binary data type (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 (hexadecimal encoded binary data)

Here is an example of a hexBinary declaration in a scheme:

<xs:element name="blobsrc" type="xs:hexBinary"/>

AnyURI data type (AnyURI Data Type) ¶

The anyURI data type is used to specify URI.

Here is an example of an anyURI declaration in a scheme:

<xs:attribute name="src" type="xs:anyURI"/>

The elements in the document should look like this:

<pic src="http://www.w3schools.com/images/smiley.gif" />

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

Miscellaneous data types ¶

Qualification of miscellaneous data types (Restriction) ¶

Restrictions that can be used with miscellaneous data types:

• Enumeration (this constraint cannot be used by Boolean data types * )

• Length (this constraint cannot be used by Boolean data types)

• MaxLength (this constraint cannot be used by Boolean data types)

• MinLength (this constraint cannot be used by Boolean data types)

• Pattern

• WhiteSpace

* translator’s note: constraint refers to constraint.
