Even in the USA, no-DME restricts the choice of a destination/alternate, IIRC.

How so?

If you're flying a GPS approach at your primary airport, the alternate
airport must have a non-GPS IAP. If the only non-GPS IAP requires DME,
then you need to have DME operational in the aircraft.

Keep in mind that I did not cite all the rules/regs concerning this
issue, just the part that illustrates this point.

Mark,

That's true for most GPS receivers certified under TSO 129, but not true
for WAAS enabled units certified under TSO 146.
