I'm having difficulty writing my xml schema (.xsd) file. My xml file contains a recursive element para which in turn has mixed elements within.
The element para contains either text only or it contains 0 or more sub-elements para and/or it contains 0 or more element footnotes or/and it contains 0 or more elements emphasis.
Footnotes in turn may contain subelement para which in turn contains text and/or footnotes and/or emphasis, etc.
Here's my abcad.xsd file
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="content">
<xs:complexType mixed="true">
