Expandable region in xml

[Sandrac]

In \[code\]C#\[/code\] I can partition my code with \[code\]#region #endregion\[/code\] keywords.Is there any keywords in \[code\]xml\[/code\] for this functionality?I don't now whether its matters or not, I'm using \[code\]Visual Studio 2010\[/code\].EDIT :For example: I have distinct but corresponding tags like these above: I want to create a region for tool_planes and collapse them. Then create a region for tool_lines, etc.\[code\] <RibbonSeparatablePopupMenu key="tool_Plane1" preferred-tool-size="Large" Type="Classic"> <RibbonGallery key="tool_Plane_Gallery1" > <RibbonGalleryCategory key="tool_Plane_Category1"> <RibbonGalleryCategoryItem key="tool_Plane_3PointPlane" /> ... </RibbonGalleryCategory> </RibbonGallery> </RibbonSeparatablePopupMenu> <RibbonSeparatablePopupMenu key="tool_Plane2" preferred-tool-size="Large" Type="Classic"> <RibbonGallery key="tool_Plane_Gallery2" > <RibbonGalleryCategory key="tool_Plane_Category2"> <RibbonGalleryCategoryItem key="tool_Plane_OrthogonalPlane" /> ... </RibbonGalleryCategory> </RibbonGallery> </RibbonSeparatablePopupMenu>\[/code\]I don't want to group them with separate xml tags
