I just stumbled on this (to my embarrassment that it hadn't occurred to me
earlier) but I consider it as a bad bug:
If you replace
<label
ref="instance('q')/lang[@code=instance('default')/lang]/q[@n='language']"
/>
with what at first sight is the equivalent
<bind id="language"
nodeset="instance('q')/lang[@code=instance('default')/lang]/q[@n='language']"
/>
...
<label bind="language" />
it doesn't behave equivalently, because the second case needs an explicit
rebuild, and apparently the first doesn't.
How can this be? A bind ought to be equivalent to the use of a ref; and
any constraint-based system should be able to tell what needs updating. Is
this really hard to fix?
