My reading of these instructions: users have 2 options, they either 
provide .xmpdata files directly or they ask LaTeX to generate it using 
filecontents* and take responsibility to remove the file when they 
change metadata.

I do not see any words discouraging the former way, while there are 
warnings concerning pitfalls with the latter approach that still may be 
convenient in some cases.

Perhaps I am wrong in my assumption that in particular case of PDF-X 
compliant documents, it is unlikely that it is just a single .tex 
document. If there are more files: graphics, custom packages, included 
.tex file then an additional separate .xmpdata file is not an issue.
