Tolerance
A Tolerance defines the permissible limit or limits of variation for defined values (e.g. a NumericalValue). The tolerated value is defined by the context in which the Tolerance is contained / used.
The values of the limits of the Tolerance, LowerBoundary and UpperBoundary, shall be interpreted as "modifiers" to the actual value. To obtain an absolute range of valid values, the values of boundaries shall be added to the actual value, regardless of the Upper or Lower prefix. For example, to define a value of 100mm with a tolerated variation between 95mm and 105mm, the definition would be Value = 100 mm, LowerBoundary=-5, UpperBoundary=+5. The Unit of the Tolerance boundaries is always the same as in the defining context.
