The Tag Library Descriptor File
The TLD file is in XML format.
It has some preamble describing the XML version and document type.
The main body is a taglib element.
This element in turn contains some global information about the library, then (most importantly) a series of tag elements.
Each tag element defines the syntax and (indirectly) the semantics of a custom tag:
- Tag name.
- Handler class.
- Attribute names and properties.
- How to deal with the element body, if there is one.
