parameter — A generic parameter of a simple type.
parameter ::= (#PCDATA)
The parameter element describes a value of a simple type, such as integer, 3-dimensional vector. The attribute names follow those of DocBook parameter.
Initialize a value of the object the parameter is mapped on by #PCDATA.
The valid name and condition depends on the parent. When the src attribute is given, an application is expected to use an external source.
NONE
Optional, ID type.
Required, the name of an object to which the parameter is mapped.
Optional, the constraint on the parameter, e.g., its unit.
Optional, type of the object within an application.
Optional, an external file that contains the data.
Reserved to refine the parameter.
The parameter element is used to set the scale of a FCC unitcell to 5.432 A.
