'display', 'display-model' and 'display-role' attributes (or properties?) 
are defined in [1]

I think that separation of 'display-model' and 'display-role'
is very reasonable.

My understanding of 'display-model' and 'orientations of flows'
is as such:

'display-model' defines layout behavior of all normal(natural)
flow elements in the container.

It is a bit different from "The 'display-model' property
determines the algorithm with which an element lays
out its children" as absolute positioned children are
not affected by container's 'display-model'. (I hope)

Second thought is more radical I would say:

'display-model' is in fact a definition of a layout manager
algorithm used by a container.
Layout managers, as an entity, is well known and time proven
concept in Java world (and not only in Java).
Standard list of Java layout managers could be
found here [2].

I think that CSS will benefit if it would be possible to say
e.g. display-model:border-layout or display-model:grid-layout

In fact current definition of display::table in CSS is just rudimental 
Java::GridLayout.
But HTML::<TABLE> element has what Java uses as a Java::GridBagLayout.

I guess that if we will modify display-model list of values as

inline-layout
block-layout (or box-layout)  - standard layout for DIV container
border-layout
flow-layout  - all children are inline-blocks
grid-layout
grid-bag-layout
card-layout (probably)
spring-layout (probably)

it will increase usability and clearness of CSS a lot.
Clearly defined, time proven and familiar concept.
