PDF 1.4 or PDF/A support

[sulphur]

ImageMagick currently writes files in pdf version 1.3. Is it any plans for implementing support for PDF/A (ISO 19005-1)? The reason I ask is that new archiving regulations in my country demands all PDF's to be in the PDF/A format (for long term storage). As I understand it, PDF/A is just a stripped down version of PDF 1.4.

ImageMagick 6.3.9-2, when released, will include support for the PDF/A format.

This is great news. However, the pdf/a produced ImageMagick 6.4.0 does not seem to be 100% valid. I ran some checks with a validator and found at least these issues:
- It reports version 1.6 (shoud be 1.4)
- The file contains a font object, but does not embed the font. pdf/a requires fonts to be embedded. (is the font object needed? the pdf contains only a raster anyway(?))
- The validator reports a missing <MarkInfo> entry
- The validator reports that a device color space is used but no or a wrong output intent is set.

I would look into this myself if I knew the ImageMagick code better, but that may take some time.
