Validator : These tags are added to validate the informaion displayed in the
component. These are the UI validators which are diferent from the declaraive
validators available from the ADF business components.
Drag and drop : These tags are added to the container component to support
drag-and-drop capabiliies.
Only the important and most commonly used components and tags are
explained in the previous list.

Have a go hero - working with the components
You can now learn about some components and their usage to get some pracice by yourself:
1. Analyze all the components explained previously and check how they behave at
runime. Try out all the components in each of the type and familiarize yourself
with them.
2. Note down the component's properies and see how it difers from the properies
of other components.
3. Add a welcome message and use the page template to the index.jspx page.
Display some informaion in the index.jspx page using the components that
we have learned.
4. Add the employee informaion to the employee.jspx page and lay out the page
properly with the components that you have learned.
EL expression
Almost all the properies in the ADF Faces components will accept values in an expression
language commonly called the EL expression. The value is evaluated at runime and the
output is dynamically assigned for the property. EL expression usage in ADF will extend
the dynamic capabiliies of ADF to another level.
