Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
Attribute “vader...""” is not serializable as XML 1.0.
This document appears to be written in Dutch. Consider adding “lang="nl"” (or variant) to the “html” start tag.
