Encoding considerations:

VectorWorks documents are binary and need appropriate encoding.

Security considerations:
    
VectorWorks documents can contain executable content in the form
of MiniPascal or VectorScript scripts contained in command palettes.
This content is never executed except at the explicit direction of
the user by double-clicking on a command. It is possible, however,
that malicious users could create scripts which would cause harm to an
unsuspecting user's local files or otherwise violate the security
of their system if they were manually executed.
    
Interoperability considerations:

VectorWorks files are fully interoperable across the Macintosh
68k/PowerPC and Windows 95/98/NT4/2000 platforms & operating systems.
