 In \in {Chapter} [modifications] we discuss several primitives that are derived
 from \PDFTEX\ and \ALEPH\ (\OMEGA). Here we stick to real new ones. In the
 chapters on fonts and math we discuss a few more new ones.

+\stoptyping
+
+This primnitive is not really needed in \LUATEX\ because you can use the callback

+makes sense. As a bonus we also provide two extra penalties:

+\starttyping

+
+\startsyntax
+\matheqnogapstep = 1000
+\stopsyntax
+
+Because a math quad from the math text font is used instead of a dimension, we

+The newly introduced attribute registers are non|-|trivial, because the value

+is generally easiest to deal with attribute lists and attributes by using the
+dedicated functions in the \type {node} library, but for completeness, here is

 Attributes appear as linked list of userdata objects in the \type {attr} field of
 individual nodes. They can be handled individually, but it is much safer and more
 efficient to use the dedicated functions associated with them.
