The plugin contains some minor flaws regarding the static binding of BaseX namespaces. A few namespaces are marked as unknown in the code, however, query execution in the BaseX backend works fine in spite of them. Also, the IntelliJ ''Find Usages'' and ''Go To'' options did not work as expected in some cases, especially with regard to functions and across modules. The plugin does not yet include a code completion feature.
Usage of functions from imported or declared namespaces that do not exist in the namespace might not be marked as unknown. To highlight invalid functions, you may enable the ''XPath and XQuery > XPST: XPath static errors > XPST0017: Undefined function'' inspection in the ''Editor > Inspections'' section.
