The attribute tag in JSF

You can already add arbitrary JSFattributes to components using theattribute tag. These end up on theattributes map. However, these will be ignored unless you implement a custom renderer to take advantage of them. They must work round existing property names on the component and result in overly verbose markup:

<x:foo>
  <f:attribute name="style" value="text: bold;">
  <f:attribute name="data-bar-baz" value="#{xxx}">
</x:foo>
