      Description

      If PDF/A file includes custom metadata and its extension schema description containing the type "closed Choice of Text", PDF/A validation using Preflight fails with NPE. The extract from stack trace:
      java.lang.NullPointerException
      at org.apache.xmpbox.xml.PdfaExtensionHelper.populateSchemaMapping(PdfaExtensionHelper.java:214)
      at org.apache.xmpbox.xml.DomXmpParser.parse(DomXmpParser.java:193)
      at org.apache.xmpbox.xml.DomXmpParser.parse(DomXmpParser.java:106)
      at org.apache.pdfbox.preflight.process.MetadataValidationProcess.validate(MetadataValidationProcess.java:66)
      at org.apache.pdfbox.preflight.utils.ContextHelper.callValidation(ContextHelper.java:74)
      at org.apache.pdfbox.preflight.utils.ContextHelper.validateElement(ContextHelper.java:88)
      at org.apache.pdfbox.preflight.PreflightDocument.validate(PreflightDocument.java:168)
      ...

      It appears, that org.apache.xmpbox.xml.PdfaExtensionHelper#transformValueType() method does not consider "closed" or "open" directives for "Choice" value type in property definition.
