% The following characters and markup can be used within the XMP data
% defined by \Author, \Title, and so on. 
%
% * All printable non-whitespace ASCII characters except
%   '%', '{', '}', '\' can be used as themselves.
% 
% * All printable non-whitespace UTF-8 encoded Unicode characters
%   from the basic multilingual plane can be used as themselves.
% 
% * As usual, consecutive whitespace characters are contracted to a
%   single space. Whitespace after a macro such as \copyright is
%   ignored. Blank lines are not permitted. 
% 
% * The following markup can be used:
%   '\ '        - a literal space  (for example after a macro)
%   \%          - a literal '%'
%   \{          - a literal '{'
%   \}          - a literal '}'
%   \backslash  - a literal '\'
%   \copyright  - the (c) copyright symbol
%
%   \sep        - only permitted within \Author, \Keywords, \Org,
%                 \AuthoritativeDomain. 
% 
% * For backward compatibility, \& and \TextCopyright are also
%   provided. Their use is deprecated.

% '&', '<', and '>' to \pdfx@amp, \pdfx@lt, and \pdfx@gt,

% Make a version of \xmp@Keywords and \xmp@Author where \sep has been
% replaced by a comma. The first is for the pdf:Keywords property,
% which accepts a comma-separated string of keywords, and seems to be
% mandatory for PDF/A-1 compliance. The second is for the dc:creator
% property. Although it is defined to be a sequence of authors, Adobe
% Acrobat will in fact ignore and delete all except the first author.
% Therefore, it's safer to always separate authors by commas.
