Quick Start (Base64): Exporting XMP metadata using the web service API

The following code example retrieves, inspects, and saves XMP metadata. (See Exporting Metadata from 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
