Help on using the <exercise> tag

The exercise tag is used to present a question or task to the reader, with an optional answer hidden from view until the reader wants to reveal it. The question or task is contained within a problem tag and the answer is contained within a solution tag, both of which are inside the exercise tag.

Example

This CNXML:


<exercise id="texas-exercise">
  <problem id="texas-problem">
    <para id="texas-problem-para">
      What is the capital of Texas?
    </para>
  </problem>
  <solution id="texas-solution">
    <para id="texas-solution-para">
      Austin is the capital of Texas.
    </para>
  </solution>
</exercise>

print-placement (optional): Determines where the exercise will be placed relative to other content in the PDF version of the document.
Possible values:
- end - When viewing the PDF version of the content, the exercise will be moved to the end of the chapter (default, except for an exercise contained in an example).
- here - The exercise will be displayed inline with the rest of the text (default for an exercise contained in an example).
type (optional): Defines the type of exercise in order to give specialized control over numbering. Exercises of the same type are labeled in series (i.e., Exercise 1, Exercise 2...). Type can be used in conjunction with label so that exercises of each user-defined type appear with their own label. Type can be any user-defined value that reflects the purpose of the exercise.
id (required): A unique identifier, whose value must begin with a letter and contain only letters, numbers, hyphens, underscores, colons, and/or periods (no spaces).
