In this paper, we propose a new complexity metric for XML Schema documents (XSD). On the contrary of the available complexity metrics, the proposed metric is based on the internal architecture of the XSD components and hence considers the complexities of its building components. The proposed metric has been demonstrated with examples. Further a comparative study with other similar metrics proves its soundness and robustness.application/pdfQA75 Electronic computers.
