[wtp-dev] JSP validation and runtime provided Tag Libraries

I have noticed that tag libraries that are copied into a web app's WEB-INF/lib directory are recognized by the JSP validator, but tag libraries that are not in WEB-INF/lib, but instead on the project's classpath are not recognized.  By "not recognized" I mean a JSP file using tags from the library has these tags flagged with an "Unknown tag" error.  If it is perhaps a performance issue to have to search all libraries on a project's classpath for TLD files, is there (or could there be) a means of registering such tag libraries such that they can be found by the JSP validator?  A runtime that provides certain tag libraries (JSTL, JSF,...) as part of the runtime would typically (I believe) contribute these libraries as part of the runtime specific classpath container (for which WTP has a mechanism for updating the classpath when the target runtime is switched on a project).  

Let me know if there is a solution for this that I am unaware of.  If not, I will open a defect.
