The following code example imports XMP metadata and saves
the new PDF file to disk. (See Importing Metadata into PDF Documents.)
/*
* Ensure that you create a .NET client assembly that uses
* base64 encoding. This is required to populate a BLOB
* object with data or retrieve data from a BLOB object.
*
* For information, see "Creating a .NET client assembly" in Programming
* with LiveCycle ES
