   This is the DTD defining the JavaServer Pages 1.1 Tag Library
   descriptor (.tld) (XML) file format/syntax.

   A Tag Library is a JAR file containing a valid instance of a Tag Library
   Descriptor (taglib.tld) file in the META-INF subdirectory, along with the
   appropriate implementing classes, and other resources required to
   implement the tags defined therein.

<!--
The taglib tag is the document root, it defines:

tlibversion	the version of the tag library implementation
jspversion	the version of JSP the tag library depends upon

shortname	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
info		a simple string describing the "use" of this taglib,
		should be user discernable
-->

<!ELEMENT tlibversion (#PCDATA) >

<!--
Describes the JSP version (number) this taglibrary requires in
order to function (dewey decimal)

The default is 1.1

#PCDATA ::= [0-9]*{ "."[0-9] }0..3
-->

<!ELEMENT jspversion  (#PCDATA) >

<!--
Defines a short (default) shortname to be used for tags and
variable names used/created by this tag library.  Do not use
white space, and do not start with digits or underscore.

#PCDATA ::= NMTOKEN
-->

<!ELEMENT shortname      (#PCDATA) >

<!--
Defines a public URI that uniquely identifies this version of
the taglibrary Leave it empty if it does not apply.
-->

<!ELEMENT uri	 (#PCDATA) >

<!--
Defines an arbitrary text string descirbing the tag library
-->

<!ELEMENT info	(#PCDATA) >

<!--
The tag defines a unique tag in this tag library, defining:

- the unique tag/element name
- the subclass of javax.servlet.jsp.tagext.Tag implementation class
- an optional subclass of javax.servlet.jsp.tagext.TagExtraInfo
- the body content type (hint)
- optional tag-specific information
- any attributes
-->

<!ELEMENT tag (name, tagclass, teiclass?, bodycontent?, info?, attribute*) >

<!--
Defines the subclass of javax.serlvet.jsp.tagext.Tag that implements
the request time semantics for this tag. (required)

#PCDATA ::= fully qualified Java class name
-->

<!ELEMENT tagclass (#PCDATA) >

<!--
Defines the subclass of javax.servlet.jsp.tagext.TagExtraInfo for
this tag. (optional)

If this is not given, the class is not consulted at translation time.

#PCDATA ::= fully qualified Java class name
-->

<!ELEMENT teiclass (#PCDATA) >

<!--
Provides a hint as to the content of the body of this tag. Primarily
intended for use by page composition tools.

There are currently three values specified:

tagdependent	The body of the tag is interpreted by the tag
		implementation itself, and is most likely in a
		different "langage", e.g embedded SQL statements.

JSP		The body of the tag contains nested JSP syntax

empty		The body must be empty

The default (if not defined) is JSP

#PCDATA ::=  tagdependent | JSP | empty

-->

<!ELEMENT bodycontent (#PCDATA) >

<!--
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)

-->

<!ELEMENT attribute (name, required? , rtexprvalue?) >

<!--
Defines the canonical name of a tag or attribute being defined

#PCDATA ::= NMTOKEN
-->

<!ELEMENT name	(#PCDATA) >

<!--
Defines if the nesting attribute is required or optional.

#PCDATA ::= true | false | yes | no

If not present then the default is "false", i.e the attribute
is optional.
-->

<!ELEMENT required    (#PCDATA) >

<!--
Defines if the nesting attribute can have scriptlet expressions as
a value, i.e the value of the attribute may be dynamically calculated
at request time, as opposed to a static value determined at translation
time.

#PCDATA ::= true | false | yes | no

If not present then the default is "false", i.e the attribute
has a static value
