Correct me if I am wrong here, here is my understanding:
1. in TLD, a <body-content> element for a simple tag can be: empty, scriptless and tagdependent. The default is scriptless.
2. in TLD, a <body-content> element for a classic tag can be: empty, scriptless, tagdependent and
JSP. The default is?
3. you can have template text, standard and custom actions, EL expressions and include directives as the body of a simple tag, and those will be evaluated or processed before the body of the simple tag is converted into a JspFragment. However, the included content must also be non-scripting.
4. a simple tag can include a classic tag, provided the body of the classic tag is non-scripting.
