Ah, the custom tag library. You do need to know that one too. Actually we are lucky that is it short.
I know I pretty much learned it from the notes. Like Ken's or someone elses.
Let's see you have the Tag tag, and underneath that you have the attribute tag that has some child tags. The attribut child tags are <rtexprvalue> for saying whether this attribute can be determined at run-time. <required> states that it must be in there.
<body-content> states what would be the acceptable stuff in between the tag. the default is
JSP.
There really isn't much more that you really need for the exam. Well that's based on the questions I received.
Good Luck
