You can create, edit and delete attribute definitions that
apply to the module, to objects in the module, or to both the module
and the objects it contains.
System attributes
System attributes are attributes that are automatically
created by Rational DOORS.
Locales for textual attributes
When you create a text, string or enumerated attribute
value, you can select the locale for the attribute. The default locale
is the current locale of the user who creates the attribute.
DXL attributes and layout DXL columns
Both DXL attributes and layout DXL columns use DXL programs
to calculate values that are displayed in the module. DXL programs
can calculate the number of days since an object was last modified,
or the number of in-links and out-links that an object has.
