ment or of its nested ILSEs, if any. The attribute does not apply to nested
BLSEs or to content items other than text.

The content is to be aligned on the start edge in the inline-
progression direction.
The content is to be centered in the inline-progression
direction.
The content is to be aligned on the end edge in the inline-
progression direction.
The content is to be expanded to fill the available width in
the inline-progression direction.
The content is to be expanded to fill the available width in
the inline-progression direction. However, some space is
also inserted at the start edge and end edge of the text.
Normally, the spacing is distributed using a 1:2:1
(start:infix:end) ratio. It is changed to a 0:1:1 ratio if the
ruby appears at the start of a text line or to a 1:1:0 ratio if
the ruby appears at the end of the text line.
Default value:
Distribute
.
This attribute may be specified on the
RB
and
RT
elements. When a ruby is
formatted, the attribute is applied to the shorter line of these two elements.
(If the
RT
element has a shorter width than the
RB
element, the
RT
element
is aligned as specified in its
RubyAlign
attribute.)
