Description of the Problem

Given this XML document:

<A1 id="1">
  <B1 id="2"></B1>
  <C1 id="3"></C1>
</A1>

and XPath Query

//*[head(./*/last()) <= 1]

BaseX gives result

<A1 id="1"><B1 id="2"/><C1 id="3"/></A1>

Expected Behavior

Should return empty result set as Saxon & Exist.

When executing //A1/*/last(), BaseX returns 2, 2; Therefore the condition is false and node A1 should not be selected.

Steps to Reproduce the Behavior

1. Create database create database test
2. Insert XML file into database put test.xml path/to/file
3. Execute XPath query xquery //*[head(./*/last()) <= 1]
