Ignored D Msr directions are adjusted and not ignored.

[nicgowans]

Description
The ignore attribute of individual D Msr Directions has no effect when adjust.exe is run. These ignored measurements are also not counted in the import.exe ignored measurement tally (reported in *.imp file). Note: The Ignore attribute for the whole D Msr functions correctly.

Thanks @nicgowans for raising this. In this case, we're seeing one of the limitations of the design of DynaML.xsd and, while it looks like a bug, it is expected behaviour. That is, despite the fact that DynaML.xsd permits the inclusion of an <ignore>*</ignore> element for each direction, the original intention for this element was to ignore the entire direction measurement. The same applies with GNSS baseline and point clusters (i.e. the <ignore>*</ignore> element is not meant to permit ignoring individual GNSS baselines or points from a cluster).

For these reasons, I'm inclined to change this issue from a bug to an enhancement, in the view that this feature can be added to support an obvious user requirement.

Thoughts?

Thanks for this, @rogerfraser. In that case changing to an enhancement makes sense.
