Which all Component Properties can be accessed in LayOut XSL

Tarp

In my LayOut XSL I want to control the width of the component based on some specific Property of the COmponent like Component Name.
I dont trust Component ID , because the ID of the Component included in the Page created on SitePublisher and the ACDTUAL ID of the Component are different.
Is there any way we can access the Name of the COmponent in my XSL LayOut?
What all Component properties can be accessed under "/Page/ComponentData/" ?

Any help will be very appreciative.
