HTML descriptors can be structured in the same way as RTF descriptors. A menu tree of several levels is used to edit the components of the main object of the descriptor. The descriptor can be complemented by texts placed before and after the texts describing the objects. It is possible to condition editing of these texts by the existence and the number of objects edited.

The multiple level tree functions in numerous cases. It is, however, sometimes desirable to structure HTML descriptors more simply, since they are included in a set of standard pages and descriptors that make up the site.

To do this, use of a single text that includes references to the object components as well as the editing conditions facilitates maintenance of these descriptors and traceability of results.
