Abstract

The Italian regulations about Web content accessibility impose HTML 4.01 strict, XHTML 1.0 strict or superior grammar validity. Such markup constraints are complied by a low percentage of Public Institution sites. In order to include the largest amount of not strict DTD sites on a synthetic, realistic representation of accessibility degree, this paper presents an experimental approach to set up parameters for making validity measures uniform, despite they are taken from evaluating different grammars. The proposed method allows for effectiveness in computing and storing information which otherwise will be quite unfeasible. Finally, the generalization of such an approach is shown to be suited for markup quality evaluations, beyond explicit law requirements.
