Primefaces <p:importEnum> <p:importConstant> expansion support

Hi,

With 20+ developers we develop JSF-Primefaces applications on a JEE-JPA-CDI stack. Switching to IDEA improved the UI-implementation roundtrip dramatically. We don't have the problem described in https://youtrack.jetbrains.com/issue/IDEA-8754. STRG+Spacebar is expanding the properties nicely.

Only pending objective I'd like to achieve is to have IDEA-support for expanding properties of the primefaces importEnum and importConstant features which are depicted here with source code:
http://www.primefaces.org/showcase/ui/misc/importConstants.xhtml
http://www.primefaces.org/showcase/ui/misc/importEnum.xhtml

E.g.
Declaration
<p:importEnum type="javax.faces.application.ProjectStage" var="JsfProjectStages" allSuffix="ALL_ENUM_VALUES" />
<p:importConstants type="org.primefaces.util.Constants" var="PFConstants" />

Usage
#{JsfProjectStages.<Cursor here>} <!-- STRG+Spacebar should suggest all Enum-Instances -->
<h:outputText value="#{PFConstants.<Cursor here>}" /> <!-- STRG+Spacebar should suggest all Constants-->

Q1: Would IDEA be prepared to add this feature?
Q2: If not, would someone mind to point me to plugin, which might serve a a blueprint for XHTML-STRG+Spacebar-Autosuggestion?

Thx in advance
Christian
