I'm sure that there are no explicit prohibitions - but, as you say, plenty of general ones. I would say that it really comes down to a case-by-case assessment of how much risk the cable would be at. Let's face it, few people would hesitate to clip a cable to a brick 'garden wall' (and I don't think any regs have ever prohibited that), yet there are 'walls and walls' and 'fences and fences' - I know some brick garden walls that would fall over if one leant against them, and some fences that would probably survive a hurricane!
We have lots of squirrels (and other nibbling creatures at times!). For nearly 20 years, we had inherited SWA along a wall (and partially a fence!) (and goodness knows how long it had been there in total!), but they seemingly didn't touch it.
