The attribute element defines an attribute for the nesting
tag. The attribute element may have several subelements
defining:

description a description of the attribute

name the name of the attribute

required whether the attribute is required or
optional

rtexprvalue whether the attribute is a runtime attribute

type the type of the attributes

fragment whether this attribute is a fragment

deferred-value present if this attribute is to be parsed as a
javax.el.ValueExpression

deferred-method present if this attribute is to be parsed as a
javax.el.MethodExpression

            <xsd:annotation>
                <xsd:documentation>
Defines if the nesting attribute is required or
optional.

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

                            <xsd:documentation>
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.
If not present then the default is "false", i.e the
attribute has a static value

                            <xsd:documentation>
Defines the Java type of the attributes value.
If this element is omitted, the expected type is
assumed to be "java.lang.Object".

Present if the value for this attribute is to be
passed to the tag handler as a
javax.el.ValueExpression. This allows for deferred
evaluation of EL expressions. An optional subelement
will contain the expected type that the value will
be coerced to after evaluation of the expression.
The type defaults to Object if one is not provided.

                        <xsd:annotation>
                            <xsd:documentation>
Present if the value for this attribute is to be
passed to the tag handler as a
javax.el.MethodExpression. This allows for deferred
evaluation of an EL expression that identifies a
method to be invoked on an Object. An optional
subelement will contain the expected method
signature. The signature defaults to "void method()"
if one is not provided.

"true" if this attribute is of type
javax.jsp.tagext.JspFragment, representing dynamic
content that can be re-evaluated as many times
as needed by the tag handler. If omitted or "false",
the default is still type="java.lang.String"
