1. A better solution for this is to add a key to \setupbackend.
2. It doesn't work because when you set the version it's too late
because ConTeXt already wrote the PDF header (the relevant code is in
lpdf-lmt.lmt).
This is a problem because when you set a PDF format the version entry is
ignored in the header (but it's correct in catalogue entry).
%% begin example
\setupbackend[format=PDF/X-1a:2003]
\starttext
Hello TeX.
\stoptext
%% end example
%% begin pdf file (snippet from the example above, compare the version
numbers)
%PDF-1.7
%ÃÏÎÔÅØÔÐÄÆ
...
<< /Lang (en) /Metadata 7 0 R /PageLabels << /Nums [ 0 << /S /D /St 1 >>
] >> /PageMode /UseNone /Pages 15 0 R /Type /Catalog /Version /1.4.0 >>
...
%% end pdf file
