Yves,
Simplified DocBook is a small subset of DocBook. There is a description of it at:
http://www.docbook.org/schemas/simplified
It can be useful for single documents (articles, etc., but not books or sets), or for situations where you'ld like to generate legal DocBook documents, but want to limit the number of elements you use.
Generally, if you don't have a particular reason for using the simplified grammar, you're probably better off using the complete grammar. In addition, at the moment, there isn't a simplified version of DocBook 5.0, which is the latest release. So, if you want to be up-to-date with the latest, you should work with the complete schema.
Hope that helps.
