87 >Not all settings of configuration items will lead to a
88 coherent configuration; for example, the use of a timeout
89 facility might require the existence of timer support, so if
90 the one is required the other cannot be removed. Coherence
91 is policed by means of consistency rules (in particular, the
92 goal expressions that appear as CDL items
107 above]). A violation of consistency rules creates a
114 >, which must be resolved in
115 order to ensure a consistent configuration. Conflict
116 resolution can be performed manually or with the assistance
120 > tools. Conflicts come in the following
133 > conflict means that
134 there is a reference to an entity that is not yet in the current
146 when a configuration item is set to a value that is not permitted
162 >evaluation exception</I
165 is caused when the evaluation of an expression would fail (for example,
166 because of a division by zero) </P
183 > goal expression </P
193 > conflict arises only rarely,
194 and corresponds to badly constructed CDL. Such a conflict can only
195 be resolved by reference to the CDL writer.</P
