This is specified in the detection rule contained in the DocBook
configuration file for XXE (XXE_install_dir/config/docbook/docbook.xxe).
Excerpt of XXE_install_dir/config/docbook/docbook.xxe:
---
<detect>
<and>
<rootElementNamespace xsi:nil="true" />
<not>
<dtdPublicId substring="true">Simplified</dtdPublicId>

You can easily see that if your existing DocBook document does not match
the above rule, the document will not be detected as being DocBook by XXE.
