Pseudo Attributes
In addition to the attributes stored on the database, there are a large number of pseudo attributes. The value of pseudo attributes is calculated at the time of making the query.
For example, the CUTLENGTH attribute on SCTN elements is a pseudo attribute calculated at the point of doing the query.
There is a lot of functionality presented via pseudo attributes. Currently there are over 1200 pseudo attributes.
Since the value of a pseudo attribute is calculated from other attributes, it is not generally possible to set their value directly.
