Thot allows you to edit elements whose type is not defined in the structure schema of the document being edited. For example, in a document Report document like this one, it is possible to create tables (see section 19), structured graphics (see section 18.1), trees (see section 18.2), mathematical formulae (see section 20) and so on.
In a document Report, you can create one of these elements in the same situations where you can create a paragraph. You can also create them in a figure and generally speaking wherever the structure schema provides an element of another nature .
When you choose ``Other'' or ``Other nature'' in the ``Insert'' menu (see section 4.3.1), another menu is displayed: it offers the other available natures . The mechanism provided by Natures allows the user to insert within a document elements whose structure schema was not already specified when the document schema was created. Thus, the user can create schemas for his own objects (see section 24 to create new schemas) and include these objects in documents with a more standard format (like this Report for example).
In addition to structured objects, you can insert non-structured objects such as images within a document. Images are considered as basic elements (see section 1) in the same way as text, mathematical symbols (see section 20) and graphical symbols (see section 18.1). An image can be inserted wherever the type Image is allowed in the structure schema. Section 17 explains how to insert images within documents.
