And maybe we want to add a test case. But that can be a follow up patch. Absolutely add a testcase if you are enhancing the xml parser to accept new tags. > I think needs to be squashed in: > > diff --git a/docs/schemas/capability.rng b/docs/schemas/capability.rng > index 06ff685..be9d295 100644 > --- a/docs/schemas/capability.rng > +++ b/docs/schemas/capability.rng If you're going to touch docs/schemas, then it would also be nice to touch the counterpart docs/*.html.in.

I think that's somewhat good (since the parameters are positional, and we insist that they come in pairs, then the pairs must be properly interleaved), but did the C code enforce that? > > But don't we rather want multiple <secmodel> elements than multiple <doi> and <model> inside one <secmodel>? Indeed - that makes the XML layout problem MUCH easier. If we add an <interleave> around the 'model' and 'doi' sub-elements, then you could write: <secmodel> <doi>...</doi> <model>...</model> </secmodel> <secmodel> <model>...</model> <doi>...</doi> </secmodel> and have an unambiguous 2-model design, without quite so much attention being placed on the exactly-one 'doi' and 'model' subelement per 'secmodel'. -- Eric Blake eblake@xxxxxxxxxx +1-919-301-3266 Libvirt virtualization library http://libvirt.org
