Way to hide repeat header for non-relevant repeat

[ebruchez]

The scenario is a repeat where all elements are marked as non-relevant.

Now, the repeat control itself is considered non-relevant if either:

• it binds to no item (no iterations)
• all of its items are non-relevant

So the issue here is: how can we make a distinction?

grid.xbl points to the repeat sequence $repeat-sequence. With this and the relevant() function, we could detect this case and hide the headers.

However, it's not perfect: if the repeat has no iterations, then what should be done?

This might point to using a visible attribue on fr:grid, to clearly control the visibility aspect only. This could also of course apply to plain (non-repeated) grids.

Added a visibility-rule to all the items in the repeat and also to the repeat-grid itself, but it's still showing the header. Would expect the header to be hidden also. Not sure if this is the same issue..

@mkooloos Yes that's probably the same issue.

Another way is to do what we do for repeated sections in 4.5: add an enclosing element. Therefore the grid and its iterations can have independent properties.

The trick will be to make this backward compatible.

Closing this one as #635 is the solution that we have chosen.

[ebruchez]

Reopening as this is a user-facing issue, while #635 is an internal or data format issue.
