* Beginning with BaseVersion 1.7, the extensions dictionary lets developers
* designate that a given document contains extensions to PDF. The presence
* of the extension dictionary in a document indicates that it may contain
* developer-specific PDF properties that extend a particular base version
* of the PDF specification.
* The extensions dictionary enables developers to identify their own extensions
* relative to a base version of PDF. Additionally, the convention identifies
* extension levels relative to that base version. The intent of this dictionary
* is to enable developers of PDF-producing applications to identify company-specific
* specifications (such as this one) that PDF-consuming applications use to
* interpret the extensions.
