Summary of Companion File Changes

This section lists the major companion file changes.

There is a new mandatory attribute, version, on the <model-companion> tag, which must have a value of "3.0".
The XML namespace attribute (xmlns) is mandatory on the <model-companion> tag.
The <client> tag no longer has an id attribute.
The <interfaces> and <interface> tags have been removed. Views are now defined within one or more <view-group> tags, which contain <*-view> tags specific to the view type.
Custom views must be explicitly declared using the <custom-view> tag, or they will not be visible in the UI.
All interface attributes now appear on the <*-view> tag, including:
- title (was text)
- id
- authorities
- default
New requires-scenarios-loaded attribute on view tags, which can be set to false to make a view available when the current scenario has not been loaded. This is useful when creating a custom view for editing model parameters before loading a scenario.
The <version> tag has been renamed to <project-version>.
The authority names listed in the authorities attribute for a view must be space-separated (previously, they could be comma-separated).
The <client-resources-local-path> tag is valid only within the <client> tag.
The <object-type-defaults> tag is obsolete; the default action when double-clicking a scenario is to open the default custom view.
The baseline-only attribute on model resources has been renamed to load-only.

The other sections of the companion file remain largely unchanged from release 2.0:
