// This is not a generic registry reader. We assume the following structure:
// Last element of Key becomes prop, first part is the path and optionally nodes,
// when the node has oor:op attribute.
// Values can be the following: Value (string), Type (string, optional),
// Final (dword, optional), External (dword, optional), ExternalBackend (string, optional),
// Nil (dword, optional)
//
// For example the following registry setting:
// [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\LibreOffice\org.openoffice.UserProfile\Data\o]
// "Value"="Example Corp."
// "Final"=dword:00000001
// becomes the following in configuration:
// <!-- set the Company name -->
// <item oor:path="/org.openoffice.UserProfile/Data">
// <prop oor:name="o" oor:finalized="true">
// <value>Example Corp.</value>
// </prop>
// </item>
//
// Another example:
// [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\LibreOffice\org.openoffice.Office.OptionsDialog\OptionsDialogGroups\ProductName/#fuse\Pages\Java/#fuse\Hide]
// "Value"="true"
// becomes the following in configuration:
// <!-- Hide Tools - Options - LibreOffice - Advanced panel -->
// <item oor:path="/org.openoffice.Office.OptionsDialog/OptionsDialogGroups">
// <node oor:name="ProductName" oor:op="fuse">
// <node oor:name="Pages">
// <node oor:name="Java" oor:op="fuse">
// <prop oor:name="Hide">
// <value>true</value>
// </prop>
// </node>
// </node>
// </node>
// </item>
//
// Third example (property of an extensible group -> needs type):
// [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\LibreOffice\org.openoffice.Office.Jobs\Jobs\org.openoffice.Office.Jobs:Job['UpdateCheck']\Arguments\AutoCheckEnabled]
// "Value"="false"
// "Final"=dword:00000001
// "Type"="xs:boolean"
// becomes the following in configuration:
// <item oor:path="/org.openoffice.Office.Jobs/Jobs/org.openoffice.Office.Jobs:Job['UpdateCheck']/Arguments">
// <prop oor:name="AutoCheckEnabled" oor:type="xs:boolean" oor:finalized="true">
// <value>false</value>
// </prop>
// </item>
//
// External (component data) example:
// [HKEY_CURRENT_USER\Software\Policies\LibreOffice\org.openoffice.UserProfile\Data\o]
// "Value"="company"
// "Final"=dword:00000001
// "External"=dword:00000001
// "ExternalBackend"="com.sun.star.configuration.backend.LdapUserProfileBe"
// becomes the following in configuration:
// <item oor:path="/org.openoffice.UserProfile/Data">
// <prop oor:name="o" oor:finalized="true">
// <value oor:external="com.sun.star.configuration.backend.LdapUserProfileBe company"/>
// </prop>
// </item>
//
// Nil example:
// Empty value (<value></value>) and nil value (<value xsi:nil="true"/>) are different.
// In case of some path settings, the base path setting has to be cleared.
// [HKEY_CURRENT_USER\Software\Policies\LibreOffice\org.openoffice.Office.Common\Path\Current\Work]
// "Value"=""
// "Final"=dword:00000001
// "Nil"=dword:00000001
// [HKEY_CURRENT_USER\Software\Policies\LibreOffice\org.openoffice.Office.Paths\Paths\org.openoffice.Office.Paths:NamedPath['Work']\WritePath]
// "Value"="file:///H:/"
// "Final"=dword:00000001
// becomes the following in configuration:
// <item oor:path="/org.openoffice.Office.Common/Path/Current">
// <prop oor:name="Work" oor:finalized="true">
// <value xsi:nil="true"/>
// </prop>
