Problem addressed

HTML 4.01 strict, XHTML 1.0 strict or superior are allowed by the Italian regulations

Distinct dominions not easily comparable

43% of Italian Public institutions homepages are declared DTD strict

Meaningful synthesis about code validity cannot simply exclude 57% of monitored Web contents

Strategy

Strategy

We issued an experimental approach, thereby defining a metrics to:

quantify expected errors on a target DTD from a different one;

evaluate 3 properties:

validity,

strictness,

markup quality.

Such a metrics can be generalized to:

approach a more general instance about comparing documents with different DTDs.

Strategy 2

We defined the expected number of errors for a given DTD as:

We called the couple: (x'i, x''i) Errors Springing Up Rate(ESUR).

They are computed, based on a wide sample of sites according to a couple of weighted averages on errors about DTDs.

a sample of 1000 Web sites has been used to compute x'i and x''i as follows:
