The core library is the poor stepchild of the HTML library the former exists entirely to support the latter. The core tags are listed in Table 4-1.

Table 4-1. JSF Core Tags
Tag	Description
`view`	Creates the top-level view
`subview`	Creates a subview of a view
`facet`	Adds a facet to a component
`attribute`	Adds an attribute (key/value) to a component
`param`	Adds a parameter to a component

`selectitems`	Specifies items for a select one or select many component

Most of the core tags represent objects you add to components:

Attributes

Listeners

Converters

Validators

Facets

Parameters

Select items

The core library also contains tags for defining views and subviews, loading resource bundles, and adding arbitrary text to a page.

All of the core tags are discussed at length elsewhere in this book.

NOTE

All tag attributes, except for var and id, accept value reference expressions. The majority of those expressions represent value bindings; a handful represent method bindings.
