Use "suggested-value" from faces-config.xml for JSF attribute suggestion

After reading this wiki entry, it looks like one property of the faces-config.xml isn't used so far, it's the "suggested-value" (see http://horstmann.com/corejsf/faces-config.html#suggested-value ). Its description is quite small and I couldn't find any real documentation about it. But we can read: "This value is advisory only and is intended for tools", and JBoss Tools is... a tool, right?

So it would be great that JBoss Tools check the presence of such a "suggested-value" inside faces-config.xml and population an "enumeration" proposal type for the corresponding attribute.

Since "suggested-value" is a string, it cannot support natively a list of suggestions, so, right now, RichFaces is using "," as a separator. Which mean having:

<property-name>severity</property-name>
<property-class&gt;java.lang.String</property-class&gt;
<suggested-value>success,info,warning,important,inverse</suggested-value>

Should be equivalent to:

<attribute name="severity">
  <proposal type="enumeration">
    <param value="success" />
    <param value="info" />
    <param value="warning" />
    <param value="important" />
    <param value="inverse" />
  </proposal>
</attribute>

What do you think?
