User Definable Parameters
For structured documentation of individual numerical and/or alpha-numerical requirements, so-called parameters are available. They have the following structure:
Figure 117: Structure of prms

* parameter

* long-name
 
* short-name
 
* description
 
* parameter characteristics

* condition
 
((* absolute value and toleranceor
 
* minimum, typical, maximum value)
 
* unit) or
 
* text
 

The following representation example can be drawn from this structure:

Defined Parameters
There are many pre-defined parameters in the MSR DOC DTD. The only difference between them and user defined parameters is that the designation (long-name element) of the parameter is pre-defined.
