A simplified DocBook subset

The Simplified DocBook DTD is a small subset of the DocBook XML DTD. The online summary shows just how small this subset is. Over the years, the notion of a "simple" DocBook subset has come up many times. It has been observed that the number of elements in DocBook can be a little overwhelming to the new user. This DTD is an attempt to make a small subset of DocBook. The goals of this subset are: Documents written in the subset must be 100% legal DocBook documents. This subset for single documents (articles, white papers, etc.), so there's no need for books or sets, just 'articles'. The markup should be the smallest practical subset, if you need richly structured markup, use full DocBook. In particular, the subset often selects a single element from a family of related elements; for example, programlisting is provided, but screen is not. The DTD must work in online browsers (it's XML not SGML). It must be small enough to download more-or-less painlessly.
