     Specify several XMP entries for inclusion in the generated PDF document.
     Properties in the following fictitious custom schema are used:
     
     Schema name: Foo Machines Schema
     Schema namespace URI: http://www.foobar.com/ns/machines/2/
     Preferred schema namespace prefix: fm
     
     Properties in this schema and their types:
     
     YearOfManufacture: Date     Complete Date according to
                                 http://www.w3.org/TR/NOTE-datetime
                                 Various formats are supported, e.g.
                                 Year (e.g. 2008)
                                 Year and month (e.g. 2008-01)
                                 Complete data (e.g. 2008-01-17)
     MachineName:       Text
     MachineNumber:     ArticleNumber (custom type)
     
     The "ArticleNumber" value type is a structured type containing the
     following fields:

     series:            Text
     model:             Text

     Since this example uses a schema beyond the set of predefined
     XMP 2004 schemas it includes a description of the custom schema
     according to the PDF/A requirements. The schema description also
     includes a description of the custom type "ArticleNumber".
