Here is a question.
<exercise>s as part of an
<exercises>element within a division, which is the typical way for creating a collection of exercises togther at the end of a division such as a chapter or section. The content of an
<exercises>division is rather limited. It can begin with an
<introduction>(perhaps a set of common instructions), followed by a mixture of
<exercisegroup>(see Subsection 16.3.1) elements, followed by an optional
<conclusion>. The sample code in Listing 16.3.1 illustrates this structure, which is rendered later as “16.4 Exercises”.
<exercises>division is to use a sequence of
<subsexercises>elements, optionally preceded by an
<introduction>and followed by a
<conclusion>. The content of a
<subexercises>element is identical to what was described above for an
<exercises>element, but we emphasize that a strong rationale for using
<subexercises>(as opposed to
<exercisegroup>) is that a
<subexercises>element can begin with a
<title>, providing a clear way of organizing the
<exercise>s for the reader.
<exercisegroup>can only be used as part of an
<exercises>element or a
<subexercises>element, however! The portion of this section headed as “16.4 Exercises” is produced using the code in Listing 16.3.1.
<exercisegroup>to be put in multiple columns, you can add a
@colsattribute to the
<exercisegroup>with value (for example)
3. The integer value of
@colsmust be between 2 and 6 (inclusive).
<reading-questions>, can be used to house
<exercise>s designed to test or guide a reader’s comprehension of the material in that division. The structure of a
<reading-questions>element is similar to an
<exercises>element, but without the grouping options of
<exercisegroup>. The portion of this section headed as “16.3.3 Check your understanding!” is produced using the code in Listing 16.3.2.
