Manipulations

PSGML has a substitute for the normal fill-paragraph. The command C-c C-q (sgml-fill-element) is uses heuristics to decide what should be a paragraph.

1. If point is in a element content, recursively fill the sub-elements.
2. Find the biggest element with mixed content containing point.
3. If the above element is mixed but contains elements with pure element content then fill what is between the pure elements as paragraphs and fill the pure elements recursively.

The command sgml-normalize will insert missing tags and expand null tags. It does not change the attribute specifications.
