Indentation plays an important part in improving the readability of textual documents, and particularly in enhancing the navigability
of programming language source code. This is also the case in the HUTN languages, and an indentation policy should be incorporated
into the producer of HUTN text.
It is quite probable that the users of the HUTN languages will be involved in the use of a number of HUTN languages, either
through the evolution of a single domain model or through the use of a number of models. This implies a need for some uniformity
between the HUTN languages. This is achieved through the use of a common basic
structure for the languages, the design of which is described in 4.1, “Overview.?
One of the major decisions made to enhance the usability of the HUTN-generated languages was to allow the use of alternative
forms (or short-hands). These configurations would involve simple syntactic extensions without changing either the larger
syntactic structure or the semantics of the language. The details of these short
hands are described in 4.2, “The Base Language.?
