Hi Everybody,
OK. We are now blessed with a relatively new Color Management scheme -- it's almost identical to Photoshop's so how good can it be.
Mostly out of curiosity, I would like to know what are the Central Spaces (aka working spaces) in Corel for RGB, CMYK, and Lab.
Some experts consider these choices to be very important. See:

It might even help to decide whether to retouch in RGB, CMYK, or Lab. (I'm a Lab person). Even more important, it may be the deciding factor for converting to and embedding profiles for processing at COSTCO.

This color management scheme is 7 years 1 month old from the release of X5, this is about 25% of the life of CorelDRAW.
Besides Corel using an ICC compliant color management method by not supporting Black Point Compensation as default the Corel and Adobe color management technology is nearly identical.
The central working spaces can be a bit convoluted to say for certain, we must add the caveat all CorelDRAW files have been named and saved.
The reason I say this is that a new UNSAVED CorelDRAW documents will function in the document working spaces in CorelDRAW however any untagged image selected as edit bitmap will open in one of the Photo-PAINT APPLICATION DEFAULT color spaces.
This is resolved by always starting a document naming and saving the document, image color spaces then travel back and forth between CD and PP as tagged.
CorelDRAW and Photo-PAINT are document color managed and as such function in the document color space or spaces independently of the application color management settings.
CorelDRAW can function in three color spaces simultaneously, Photo-PAINT only in one.
The document working spaces are as shown in the inserted document cm dialog.
The application default color management settings basically function as a base reference set of color spaces for new documents (which can be ignored for specific color spaces) and to set specif0ic actions such has how to handle specific color management controls. I.E. how to handle missing profile, convert grayscale, color engines, rendering intents ECT.

Ariel I believe that book while being very good does not explain the issue. I've been thinking on this and from a historical perspective the internal working space is a concept from the early days when the graphics world was not color managed as we understand it today and in those days there were LUT's and internal profiles that were used. As we all know there had to be some color management and that's how they did it back then.
CorelDRAW used a 1.8gamma grayscale for grayscale that the user had no access to, if my memory still works there was a time when Corel used their own internal sRGB and in the early days a LUT and a sRGB that the user had no access to.
So from that perspective I understand the question about what internal color space the application uses.
With that said it has been nearly twenty years since that condition existed within CorelDRAW and over ten years since the current process was implemented.
About eighteen years ago the working RGB and CMYK profiles were available to the user only the grayscale was not.
Ten years ago all profile became available to the user and all the (old style) internal profiles are in the document color management dialog. CorelDRAW still utilizes the original LUT for RGB conversions for the engraving business to simulate (what they call ) color management off.
