Tag Files and jsp implicit objects

Hi,

HFSJ mentions - request and response implicit objects are available in tag files because even though it’s a .tag file it is going to end up as a part of a JSP.
if this reasoning is correct then why other JSP implicit objects - pageContext, config, application ect are unavailabe ?? after all its going to be a part of the jsp and will end up in the service method of the container generated servlet.

Thanks
Sameer

the config, application, session and out implicit objects are available in a tag file. Only instead of pageContext, there's jspContext...

there should be a correction in the book i guess but then again why is that pageContext is not available after all the underlying servlet will be setting this object
