loose DTD: H1 element

H1

The six heading elements, <H1> through <H6>, denote section headings. Although the order and occurrence of headings is not constrained by the HTML DTD, documents should not skip levels (for example, from H1 to H3), as converting such documents to other representations is often problematic.

Example of use:

    <H1>This is a heading</H1>
    Here is some text
    <H2>Second level heading</H2>
    Here is some more text.
