|

|
|
<div><p>RFML documents, called RFML source files, contain tags that define
|
||
|
|
the specification for a particular data format.</p>
|
||
|
|
<div class="section"><p>Because RFML is based on PCML, the syntax is familiar to PCML
|
||
|
|
users. Because RFML is an XML extension, RFML source files are easy to read
|
||
|
|
and simple to create. For example, you can create an RFML source file by
|
||
|
|
using a simple text editor. Also, RFML source files reveal the structure
|
||
|
|
of the data in a way that is easier to understand than in a programming language
|
||
|
|
like Java™.</p>

<div class="section"><p>The <a href="rfmldtd.htm#rfmldtd">RFML document type definition

parser can validate your RFML source file at runtime, declare the RFML DTD

a named structure that you can reuse within the RFML source file. The structure
