Binary data types are used to represent binary values.

Binary Data Type

The binary data types are used to represent binary values. Two binary types are common in use:

• base64Binary: represents base64 encoded binary data
• hexBinary: represents hexadecimal encoded binary data

Let's see an example:

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

and an element in your XML document look like this:

<blob>9FEFE</blob>
