The taglib tag is the document root, it defines:

tlib-version	the version of the tag library implementation

jsp-version	the version of JSP the tag library depends upon

short-name	a simple default short name that could be used by
		a JSP authoring tool to create names with a mnemonic
		value; for example, the it may be used as the prefered
		prefix value in taglib directives

uri		a uri uniquely identifying this taglib

display-name    the display-name element contains a short name that
                is intended to be displayed by tools

The tag defines a unique tag in this tag library.  It has one
attribute, id.

The tag element may have several subelements defining:

name              The unique action name

tag-class         The tag handler class implementing
                  javax.servlet.jsp.tagext.Tag

                  javax.servlet.jsp.tagext.TagExtraInfo

JSP		The body of the tag contains nested JSP syntax

empty		The body must be empty

The default (if not defined) is JSP

The variable tag provides information on the scripting variables
defined by this tag.  It is a (translation time) error for a tag
that has one or more variable subelements to have a TagExtraInfo
class that returns a non-null object.

The subelements of variable are of the form:

name-given               The variable name as a constant

name-from-attribute      The name of an attribute whose (translation
                         time) value will give the name of the
                         variable.  One of name-given or
                         name-from-attribute is required.

variable-class           Name of the class of the variable.
                         java.lang.String is default.

declare                  Whether the variable is declared or not.
                         True is the default.

scope                    The scope of the scripting varaible
                         defined.  NESTED is default.

description              Optional description of this variable

The name for the scripting variable.  One of name-given or
name-from-attribute is required.

<!ELEMENT name-given (#PCDATA) >

<!--

the name of the variable.  One of name-given or name-from-attribute
is required.
-->

<!ELEMENT name-from-attribute (#PCDATA) >

<!--

The optional name of the class for the scripting variable.  The
default is java.lang.String.

TagExtraInfo for details.  This element is optional and "true"
is the default.

The scope of the scripting variable.  See TagExtraInfo for details.
The element is optional and "NESTED" is the default.  Other legal
values are "AT_BEGIN" and "AT_END".

The attribute tag defines an attribute for the nesting tag

An attribute definition is composed of:
	
- the attributes name (required)
- if the attribute is required or optional (optional)
- if the attributes value may be dynamically calculated at runtime
  by a scriptlet expression (optional)
- the type of the attributes value (optional)
- an informal description of the meaning of the attribute (optional)
