             Summary: Custom XMP Extension Schema dropped when generating PDF/A-2a and PDF/UA-1 compatible PDF
                 Key: FOP-3304
                 URL: https://issues.apache.org/jira/browse/FOP-3304
             Project: FOP
          Issue Type: Bug
    Affects Versions: 2.11, 2.10
            Reporter: Michael Schubert
         Attachments: FOP_Test.zip, veraPDFValidationReport.xml

I am using fop 2.10 to generate a PDF-File which needs to be compatible with both PDF/A-2a and PDF/UA-1.

The resulting file passes the PDF/UA-1 check, but fails the PDF/A-2a verification because of rule 6.6.2.3.1:
 * Test number1: "XMP property is either not predefined, or is not defined in any XMP extension schema";
 * Test number 2: "XMP property does not correspond to type null".

The offending property is {{{}myschema:CustomProp{}}}, which is correctly defined in the fo-file, but somehow seems to be dropped when the document is created with both PDF/A-2a and PDF/UA-1 profiles activated. Actually, my custom XMP extension schema definition for schema "{{{}myschema{}}}" seems to be replaced by the definition of the schema "{{{}pdfuaid{}}}", which is automatically generated into the PDF.

I reproduced the problem using the files in the attached zip-archive.

Using the same {{report_test.fo}} as input, I started {{fop}} three times:
 # with {{-c cfg_a_2a.xml}} (configuration file which only activates the PDF/A-2a mode)
*Result:* {{test_1_a_2a.pdf}} - {color:#00875a}passes the PDF/A-2a validation{color}
 # with {{-c cfg_ua_1.xml}} (configuration file which only activates the PDF/UA-1 mode)
*Result:* {{test_1_ua_1.pdf}} - {color:#00875a}passes the PDF/UA-1 validation{color}
 # with {{-c cfg.xml}} (configuration file which activates both the PDF/A-2a and the PDF/UA-1 modes)
*Result:* {{test_1.pdf}} - {color:#FF0000}passes the PDF/UA-1 validation, but not the PDF/A-2a validation{color}

see the attached veraPDFValidationReport.xml
