Anything the font creator/vendor wishes to attach to the font file.  
Perhaps a serial number, for example.

Note that no browser or other agent will pay any attention to it; this  
is not a potential DRM mechanism, and the data in that block has no  
meaning to anyone except its creator. Browsers and similar tools are  
required to ignore it; they cannot expect to know what it means.

In a sense, this does not provide anything more than a vendor can  
already do with standard OpenType, by putting the same data into a  
private table within the font (or even inserting it between the  
tables). It is provided separately in WebOTF because this allows it to  
be added separately from the main OpenType font build process, which  
may simplify workflow and testing at least for some vendors.
