org.apache.xmlbeans.QNameSet
This interface represents a lattice of finite and infinite sets of QNames. The lattice the minimal one that is closed under union, intersection, and inverse, and contains individual QNames as well as entire namespaces. Here is a summary of the two kinds of QNameSets:
- A QNameSet can cover a finite set of namespaces, additionally including a finite set of QNames outside those namespaces, and with the exception of a finite set of QNames excluded from those namespaes:
  - excludedQNamesInIncludedURIs == the set of excluded QNames from coveredURIs namespaces
  - excludedURIs == null
  - includedURIs == the set of covered namespace URIs
  - includedQNamesInExcludedURIs == set of additional QNames outside coveredURIs namespaces
- A QNameSet can cover all namespaces except for a finite number of excluded ones, additionally including a finite set of QNames within the excluded namespaces, and with the exception of a finite set of QNames outside the excluded namespaces:
  - excludedQNamesInIncludedURIs == the set of excluded QNames outside uncoveredURIs namespaces
  - excludedURIs == the set of uncovered namespace URIs
  - includedURIs == null
  - includedQNamesInExcludedURIs == set of additional QNames from uncoveredURIs namespaces
Notice that a finite set of QNames is a degenerate case of the first category outlined above:
- A QnameSet can contain a finite number of QNames:
  - excludedQNamesInIncludedURIs == null
  - excludedURIs == null
  - includedURIs == empty set
  - includedQNamesInExcludedURIs == set of included QNames
