Issue 133: Rewrite scope note of E54 Dimension
.....An instance of E54 Dimension is thought to be the true quantity, independent from its numerical approximation, e.g. in inches or in cm.
....The properties of the class E54 Dimension allow for expressing the numerical approximation.
1. Change: "is thought to be"
2.Rewrite phrase "The properties of the class E54 Dimension allow for expressing the numerical approximation."
3. Examples are wrong, should imply the measured object.
4. Revise definition of number.
See discussion, Steve will rewrite the scope note to include the notion of number.

New Scope Note
E54 Dimension
This class comprises quantifiable properties that are measured by some calibrated means and can be approximated by numerical values.
An instance of E54 Dimension is regarded as the true quantity, independent from its numerical approximation, e.g. in inches or in cm. The properties of the class E54 Dimension allow for expressing the numerical approximation. It is recommended to record all numerical approximations of instances of E54 Dimension as intervals of indeterminacy. Numerical approximations in archaic instances of E58 Measurement Unit used in historical records should be preserved. Equivalents corresponding to current knowledge should be recorded as additional instances of E54 Dimension as appropriate.
