The predicate html/4 implements HTML quasi quotations. These quotations produce a DOM term that is suitable for html//1 and other predicates that are declared to consume this format. The quasi quoter only accepts valid, but possibly partial HTML documents. The document must begin with a tag. The quoter replaces attributes or content whose value is a Prolog variable that appears in the argument list of the html indicator. If the variable defines content, it must be the only content. Here is an example, replacing both a content element and an attribute. Note that the document is valid HTML.
