The Android manifest is built under the hood by the Delphi compiler. A template manifest contains things like <%uses-permission%>, <%services%> and <%provider%>. These are replaced in the build process with the appropriate entries to produce the manifest which is included in the software package.
If you want to make changes to the final manifest (as some sample service projects suggest) you need to edit the template.
Giving Delphi the information to correctly populate the final manifest is also a bit convoluted
