XML　has　become　the　de　facto　standard　for　representing　and　interchanging　data　in　internet-based　applications.　The　wide　use　of　XML　has　necessitated　the　XML　document　semantically　richer.　The　integrity　constraints　play　an　important　role　in　relational　world.　And　the　integrity　constraints　for　XML　have　been　widely　investigated　over　the　past　few　years,　especially　the　functional　dependencies　and　multi-valued　dependencies.　However,　there　are　few　researches　on　inclusion　dependencies　for　XML　(XINDs).　In　this　paper,　we　propose　a　novel　approach　for　defning　XINDs　in　XML　Schema,　which　is　based　on　paths.　We　employ　two　existing　components,　selector　and　field,　to　locate　the　information　items,　which　uses　restricted　XPath　as　path　description　language.　In　particular,　we　extend　the　semantics　of　the　field　components　to　support　a　set　(list)　of　nodes　and　node　with　complex　type.　Related　issues　are　discussed,　such　as　dealing　with　null　values　and　comparing　element　nodes　with　complex　type.　©　2010　IEEE.
