  A length parameter is specified like
  

  
  

          annotation { "Name" : "My Length" }

          isLength(definition.myLength, LENGTH_BOUNDS);
  
  That LENGTH_BOUNDS is just a map, and you can write your own. For example:
  

  
  

          annotation { "Name" : "My Length" }

          isLength(definition.myLength, { (centimeter): [0, 1, 500] } as LengthBoundSpec);

  A good autocomplete for this is "Length parameter (custom bounds)" so you can fill in the following:
  
  

      annotation { "Name" : "My Length" }
          isLength(definition.myLength, { (inch) : [ -10000, /* min (inclusive) */
                                                     1.0,    /* default */
                                                     10000   /* max (inclusive) */ ] } as LengthBoundSpec );

  
  

  One thing to keep in mind is that your defaults can be different in workspaces using different units, which you can do by adding more items to that map. This helps avoid issues where you see defaults with strange decimal values. For example, the default LENGTH_BOUNDS is defined as:
  
  

  export const LENGTH_BOUNDS =
  {
      (meter)      : [-500, 0.025, 500],
      (centimeter) : 2.5,
      (millimeter) : 25.0,
      (inch)       : 1.0,
      (foot)       : 0.1,
      (yard)       : 0.025
  } as LengthBoundSpec;

  ok, that's the first step in the right direction! Thank you very much for that!

  If now the values could stand as variable (default, min, max) in the tolerance definition, then I would be again a step further.
