Implementation:
This implementation maps all primitive values to a uri. Model structure is determined by ordering of list and by the
uri itself, as it is easy to determine children and parents.

Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection, Value = null
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency, Value = null
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency/version, Value = 1.4
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency/artifactId, Value = artifact-dep
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency/groupId, Value = org.apache.maven.dep
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency/scope, Value = compile
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency/version, Value = 1.1
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency/artifactId, Value = artifact-dep
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency/groupId, Value = org.apache.maven.dep
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency, Value = null
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency/version, Value = 1.0
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency/artifactId, Value = bogus-dep
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency/groupId, Value = org.bogus
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency, Value = null
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency/version, Value = 1.1
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency/artifactId, Value = artifact-dep
Uri = http://apache.org/model/project/dependencyManagement/dependencies#collection/dependency/groupId, Value = org.apache.maven.dep
Uri = http://apache.org/model/project/dependencies#collection, Value = null
Uri = http://apache.org/model/project/dependencies#collection/dependency, Value = null
Uri = http://apache.org/model/project/dependencies#collection/dependency/artifactId, Value = org.apache.maven.dep
