<schema xmlns=http://purl.oclc.org/dsdl/schematron queryBinding="xslt3">

  <let name="department-code" value="/inventory-list/@depcode"/>

  <pattern>
    <rule context="article">

      <let name="article-code" value="@code"/>

      <assert test="starts-with($article-code, $department-code)">

1st Chapter 1, the section titled “The oXygen IDE” and Chapter 4, the section titled “IDE based Schematron validation” (pages 6 and 35 in the print edition) In both places, replace the sentence: “As far as I know, the only IDE currently available (2022) that supports Schematron this way is oXygen.” with:

“As far as I know there is currently (2023) one other IDE that also supports Schematron validation in the editor: XMLBlueprint (https://www.xmlblueprint.com/).”

1st Appendix A, Example A.21 (page 171 in the print edition) In Example 1.21 /message/ should be /messages/:

/messages/*[@default eq 'true']/message

 Confirmed May 30, 2023 Danny MacMillan
1st Appendix A, Figures A9, A10, A11 (pages 171–172 in the print edition) The titles of all three begin with /*/messages. They should begin with /messages/*. Confirmed May 30, 2023 Danny MacMillan
1st Appendix A, Examples A.22–26 (pages 173–174 in the print edition) All four examples start with /message/*. They should start with /messages/* instead. Confirmed May 30, 2023 Danny MacMillan
1st Appendix A, Example A.27 (page 175 in the print edition) The test attribute in the <assert> element includes an extra closing parenthesis. The test should be:

test="string-length(.) lt 25"

The second bullet point after Example A.27 has the same problem.

 Confirmed May 30, 2023 Danny MacMillan
1st Appendix A, second bullet point after Example A.27 (page 175 in the print edition) The predicate at the end of this bullet point starts with /message/". It should be /messages/":
