To whom it may concerns

In the chapter 15.2.2 three ways of populating the taglib map are listed:
- explicit mapping;
- implicit mapping;
- well-know URI's.
In the implicit mapping paragraph it reads that 'the container reads all the taglib.tld files present in the packaged JARs', but nohing more is said.
According the 'JavaServer Pages Version 2.0'(jsp-2_0-fr-spec.pdf), chapter 'JSP.7.3.4 Implicit Map Entries from TLDs', implicit mapping includes also another mechanism: 'The container searches for all files with a .tld extension under /WEB-INF or a subdirectory,...' .
The chapter 15.2.2 does not report anything about that useful mechanism.
Nevertheless the example of Simple Tag in the chapter 17.2.1 seems to exploit it.
