thank you
it looks valuetype element may in wrong place or need additional valuetype elements @ root of element describes pdfaschema.
in example, have pdfaschema defined as
<rdf:li rdf:parsetype="resource"> <pdfaschema:namespaceuri>http://ns.adobe.com/pdf/1.3/</pdfaschema:namespaceuri> <pdfaschema:prefix>pdf</pdfaschema:prefix> <pdfaschema:schema>adobe pdf schema</pdfaschema:schema> <pdfaschema:property> <rdf:seq> <rdf:li rdf:parsetype="resource"> <pdfaproperty:category>internal</pdfaproperty:category> <pdfaproperty:description>a name object indicating whether document has been modified include trapping information</pdfaproperty:description> <pdfaproperty:name>trapped</pdfaproperty:name> <pdfaproperty:valuetype>text</pdfaproperty:valuetype> </rdf:li> </rdf:seq> </pdfaschema:property> </rdf:li> inside rdf:li element (and other two), looks need additional pdfaschema:valuetype element. not sure correct specification though , acrobat not seem write out these additional elements when converting pdf/a.
