Prerequisites
Void elements
Void elements must always have a trailing slash.
<!-- Good -->
<status value="true" />
<!-- Bad -->
<status value="true">
Here be dragons. Unlike in HTML5, you really do need those closing slashes. XML is super strict.
Attributes
Use double-quotes for attribute values (not single-quotes).
<!-- Good -->
<status value="true" />
<!-- Bad -->
<status value='true' />
Indentation
Use 4 spaces (not tabs) for indentation.
<status>
••••<value>true<value>
