Ok, so basically the same situation we have now. You have to figure out |
| 15 |
where to get the rng and supply it manually... |

But does it /complain/ about the xml-model? Is it safe to add that to |
| 36 |
our XML files (in terms of tooling and stability of the spec)? If so, I |
| 37 |
can at least script the validation: parse the href from xml-model, fetch |
| 38 |
it somehow, run it through rnc2rng, and then pass it to xmllint. |
| 39 |
|
| 40 |
Or we could even generate the rng files automatically and host them like |
| 41 |
we do the DTDs to skip a step. |
