Convert rgb jpeg to cmyk pdf no embedded profile

[stroker]

When i use the below command the profile does not get embedded. If I change to output.tif there is no problem, the image gets converted to cmyk with right embedded profile.
Input.jpg have srgb icc profle.

convert input.jpg -profile CoatedFOGRA27.icc output.pdf

I'm using version 6.4.0, should I try a newer version or what can be the problem?

ImageMagick does not embed the color profile into a PDF image at this time. We believe we need to create an XMP profile and embed the ICC profile within it. If you know of a better way we will investigate supporting embedding color profiles in PDF.

Ok thanks. I solved the problem using ImageMagick to convert the images to the right profile then used a PDF library to mount the images.
It seems that the PDF itself don't need an embedded profile.
