 Figure 5.37 illustrates how the PaintComposite table is used in combination with
 content sub-graphs to implement an alternate compositing effect. The source
 sub-graph defines a green capital A; the backdrop sub-graph defines a black

 [Scalable Vector Graphics (SVG)][31] supports alpha channel masking using the
 <mask> element. The same effects can be implemented in COLR version 1
 using a PaintComposite table by setting a pattern of alpha values in the source
-sub-graph and selecting the source in composite mode. This is illustrated in
+sub-graph and selecting the *Source In* composite mode. This is illustrated in
 figure 5.38.
