Here are some issues you might encounter while working with dates:

After running Right click on file name in project pane -> "Transform" -> "Transform with..." -> "Update FRUS document dates," you might receive the following error message:

System ID: /Users/waxcylinderrevival/workspace/hsg-project/repos/frus/schema/saxon-configuration.xml
Scenario: Update FRUS document dates
XML file: /Users/waxcylinderrevival/workspace/hsg-project/repos/frus/volumes/frus1927v03.xml
XSL file: /Users/waxcylinderrevival/workspace/hsg-project/repos/frus/schema/update-frus-doc-dates.xsl
Engine name: Saxon-EE 9.6.0.7
Severity: warning
**Description: Invalid configuration property xquery/@version. Supplied value '3.1'. languageVersion = 3.1**
Start location: 4:28

If you scroll to the encodingDesc/classDeclsection of your chosen document, you might see the classDecl/xi:include reference has been replaced with the full taxonomy.

Example:

<classDecl>
  <taxonomy xml:id="frus-dates" xml:base="../shared/frus-dates.xml">
    <category xml:id="date_apparent-typo-based-on-document-content">
      <catDesc>The recorded date was determined to be an error via content of the
        document and corrected Date value(s) were inferred from the content of
        the document</catDesc>
    </category>
    <category xml:id="date_apparent-typo-based-on-document-scan">
      <catDesc>The recorded date was determined to be an error via scanned version
        of the original document and corrected Date value(s) were inferred from
        the content of the scanned document</catDesc>
    </category>
    ...
  </taxonomy>
<classDecl>

1. Replace classDecl/taxonomy with:

<classDecl>
  <xi:include href="../shared/frus-dates.xml" xpointer="frus-dates"/>
</classDecl>
