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
