PDF files have a rendering intent as part of the file specification. In
other words, there is never any question as to what rendering intent a
particular object should use, because the PDF graphics state has a
rendering intent, and its default is Relative Colorimetric. You can
override the rendering intent on a single-object conversion by using the
touchup object tool, then right-click and go to the properties panel and
select the "color" tab. The rendering intent of the object selected is
reflected in the panel, and you can change it before clicking "Convert
Colors."

When we talk of "device-indepenent color" we mean that colorspaces have
profiles associated with them, so that we know what the numbers mean.
"Device-independent profile" is probably a documentation error--there's
no such thing, except for abstract profiles, which almost no application
supports. So, Calibrated CMYK does makes sense. (Was this explanation
about "device-indpendent profiles" in Acrobat's documentation?)
