This template standardizes the declaration of constraints. It became necessary to process the default values.

The template has 4 unnamed Parameters and a named one:

# is the attribute ''optional'' (default) or ''required''?
*'''default''': the default vaue (optional), e.g. ''TRUE''

Usage

This template standardizes the declaration of constraints. It became necessary to process the default values.

Parameters

The template has 4 unnamed Parameters and a named one:

  1. The attribute name to which the constraint applies
  2. xsd for standard types like string and boolean resp. rml for generic railML® types like tGenericRef
  3. the type, e.g. string or tGenericRef
  4. is the attribute optional (default) or required?
  • default: the default vaue (optional), e.g. TRUE

Examples

*{{constraint|vehicleRef|rml|tGenericRef|mandatory}}

delivers

*{{constraint|vehicleCount|rml|tCounter|default=1}}

delivers

*{{constraint|frontGangway|xsd|boolean}}

delivers
