Attributes with multiple values

You can have more than one value for a select attribute. The different values are stored in the one attribute, separated by spaces.

In many cases, you may want to apply more than one value to a metadata attribute. For example, a paragraph may relate to audiences of both admin and manager.

Attributes can take more than one value. Spaces are used as delimiters, to separate the different values. For example, a paragraph with two audience values would be marked up as:
<p audience="admin manager">The installation...</p>

Obviously, then, individual values of metadata attributes must not contain spaces.
