\subsection{Model Containers}
In addition to the general inheritance rules, there is also the concept of Model Containers, which allow the framework to delegate to specific model container implementations the decision of whether \#collections and \#sets should be joined, deleted, or have no operation applied. This will be covered more fully in section 3.
\subsection{Mixins and Multiple Inheritance}
Currently, Maven 3.0 supports linearlized inheritance, making mixins and multiple inheritance easy. Support for multiple inheritance would require an additional to the pom, within the parents section.

\subsection{Inheriting Version and Group Ids}
If \emph{project.version} is not specified within the child pom, the child pom will use the \emph{project.parent.version} as its own version. Similarly, if \emph{project.groupId} is not within the child pom, the child pom will use the \emph{project.parent.groupId} as its own \emph{project.groupId}.

A child project does not inherit the following properties from its specified parent project. All other properties are inherited, unless otherwise noted below.
A child project does not inherit the following properties from its specified parent project\footnote{Technically, project.version, project.groupId and project.artifactId are not inherited from the parent pom. They do, however, have the values of project.parent.version, project.parent.groupId and project.parent.artifactId implicitly applied from the same pom.}.

A parent project can set an inherited property within the following elements of the pom. This will mark the container as private, thus preventing inheritance:

Within the project there are a number of nodes which contain id. These nodes may be inherited or even joined.
Within the project there are a number of nodes which contain id. Each of the nodes below is an element of a collection, meaning there may be more than one. The ID is used to determine whether the containers should be joined, rather than just added to the collection..
