Here's another of my lists. This one is of those things that are mildly discouraged in XML because they aren't interoperable with old SGML tools. 1. If an element is declared EMPTY, always use <tag/> rather than <tag></tag>. 2. If an element is not declared EMPTY but has in fact no content, always use <tag></tag> rather than <tag/>. 3. Don't reference parameter entities in content models that are empty, or begin or end with "|" or ",". 4. Don't use multiple ATTLIST declarations for a given element type. 5. Don't declare an attribute in more than one ATTLIST declaration. 6. Don't use ATTLIST declarations that don't declare any attributes. 7. Don't declare two different enumerated attributes that have overlapping possible values. 8. Always declare the entities amp, lt, gt, quot, and apos if you reference them. -- John Cowan http://www.ccil.org/~cowan cowan@c... You tollerday donsk? N. You tolkatiff scowegian? Nn.
