Digital XLR vs. Analog XLR - Balanced Cables


What is the difference between a digital XLR/balanced cable and an analog XLR/balanced cable?

What if I used an analog XLR/Balanced cable to carry a digital signal from the digital output of one device to the digital input of another device?

Any risks/damage, etc. . .

I don't see reason why any company would use oversized foamed teflon tubes and 99.9999999% pure copper in digital cable but if you say they do - I trust you.
Ckoffend - Purcell, being upsampling DAC (and not oversampling), most likely rejects jitter. Quality and type of cable might be not very important (it isn't with my Benchmark - also upsampling DAC).
The temporary cables that I have tried, to confirm that I am getting the full 24/192 upsampling sound very good. As I previously mentioned, to upconvert to this level, it is required that I used two balanced digital cables to handle the full bandwidth. DCS indicates that it is impossible to transmit this amount of bandwidth on either a Coax digital cable, a glass optical digital cable or a single balanced AES/EBU cable. I don't necessarily question this, but before spending a several hundred dollars per cable, I wanted to be sure that the two appropriate cables would actually deliver the required upsamping level I wanted to hear/test. Since I have plenty of balanced analog cables, I was just seeking a reasonable and fast opportunity to test.
I don't know why DCS want to transfer signal on two cables (Benchmark uses one for 24bit/192kHz) but jitter rejection properties might make cable discussion irrelevant.
Ckoffend-

You can try them; they should work. You have nothing to lose.

OTOH, I would be more certain that digital cables would work for analog.
