Called by classes that implement
FaceletHandler in their implementation of apply().
If the argument comp is new to the view, for each tag attribute declared to be in the pass through attribute
namespace, set the name and value of the attribute into the pass through attributes map of the component. See
UIComponent.getPassThroughAttributes(boolean). See the VDLDocs for the namespace URI of the pass through
attribute namespace. Attributes whose value is a ValueExpression must remain un-evaluated and stored in the
map as ValueExpression instances.
