Default combining method
If you have more than one descriptor in a <description> element, then you must use either the default combining method described in this section or the uselogic attribute described in The uselogic attribute.
The default combining method uses:
- The boolean result for each individual descriptor (see Evaluation of individual descriptors)
- The value of the invertmatch attribute in each individual descriptor
- The value of the Optional attribute in each individual descriptor
- The default combining rule
