Elements that have ATTLIST tags contain attributes (name-value pairs). For example:
<!ATTLIST JDBCRESOURCE
jndiname CDATA #REQUIRED
poolname CDATA #REQUIRED
enabled %boolean; "true">
A JDBCRESOURCE element can contain jndiname, poolname, and enabled attributes.
The #REQUIRED label means that a value must be supplied. The #IMPLIED label means that the attribute is optional, and that Sun Java System Web Server generates a default value. Wherever possible, explicit defaults for optional attributes (such as "true") are listed.
Attribute declarations specify the type of the attribute. For example, CDATA means character data, and %boolean is a predefined enumeration.
