Removed setting of sf.project.type, as it's the same for all these projects, so can be done in the sf-platform config file.

Added helix packasge (now added to cache).

Sorted this sources csv file to match the order in the prebuilt system definition. This means that a system defintion which is collated from the peices in the csv file comes out the same as the prebuilt version, which verifies that it's all OK.

Corrected tech domains for packages where they were wrong, and added them where they were missing.

Moved packages in tools and ostools repository locations into the (new) corresponding layers of the model.

Moved conntools into "app" layer to match the repository location. (This is subject to a further change shortly when the repository will change to reflect it moving from the app to mw.)

Removed top-bit-set characters from the middle of "Implementation". Moved a few of the attributes in the tags, so that they follow a consistent order.

Reverted to revision of system model where items are in the "correct" (non-alphabetical) order, according to the way in which it will draw the pictoral model and the sequence in which it would need to build things (when building sequentially rather than with Raptor).
