There is no text after the "Generalization:" label in the EmbeddedValue section.

The accuracy attribute for DatatypeDefinitionReal does not indicate what it measures or what the units are. It might be understood as the size of the Real data type in bits or bytes, or the length of the mantissa, or the number of bits or digits that can be represented without loss of accuracy, or perhaps other measures of floating-point accuracy.

Section 10.8.3 indicates that AttributeDefinition specializes AccessControlledElement, which in turn specializes Identifiable, but this not reflected in Figure 10.3.

Figure 8-1 has a low resolution which makes text on it hard to read.
