In my XML editor I would have been using a DTD that would have allowed me to not only mark up each special word throughout the document but also indicate what type of word it was. Then, when it came time to actually publish the document on the Web, I would have used an XSL style sheet that would have allowed my document to be transformed into the needed HTML format for display on the Internet. With some additional Perl scripts the entire rendering process, including building the master index, could be automated, making the process of editing the document much easier. I used two new acronyms, DTD and XSL, which I will explain below. There must be a root element in which all other elements of the document are contained.
Some text goes here.
There can be no overlapping of elements. All elements must be properly nested. A closing tag for a child element can never fall outside the parent element. The XML specification is 32 pages long so there is obviously more to it than this. That is what the DTD is for.
