Constructor for TagFileInfo from data in the JSP 2.0 format for TLD. This class is to be instantiated only from
the TagLibrary code under request from some JSP code that is parsing a TLD (Tag Library Descriptor).
Note that, since TagLibibraryInfo reflects both TLD information and taglib directive information, a TagFileInfo
instance is dependent on a taglib directive. This is probably a design error, which may be fixed in the future.
name - The unique action name of this tag
path - Where to find the .tag file implementing this action, relative to the location of the TLD file.
tagInfo - The detailed information about this tag, as parsed from the directives in the tag file.
