The Modelica community has long pursued the vision of Integrated Whole Product Modelling. This implies the ability to integrate best practice modelling languages and techniques. With ModelicaML a first step towards an open integration within the sphere of the Eclipse Modelling Framework exists. This paper argues for a development direction of ModelicaML that creates a small core with well-defined semantics; instead of the current version that is based on an extension of SysML. To this end; modelling standards and their practicabilities are discussed and exemplified through a usage scenario.
