Appendix A.1 Validating MAF documentsISO: Validating MAF documents¶

For validating MAF document, the first step is to convert the RELAX NG compact schema into an XML RELAX NG schema (for instance using trang). Such a XML RELAX NG schema may be found at maf.rng

Then, the validation may be performed, for instance, using xmllint (from libxml2).

xmllint --relaxng maf.rng mafdoc.xml

It should be noted that some semantics constraints of MAF are not checked by the RELAX NG schema, in particular the constraint between the word form and token paths expressed in Section 9.3.2.
