+the workspace will be dumped. This means that properties of the workspace\r
+itself will be lost.</p></div>\r
+<div class="paragraph"><p>This is relevant for, e.g., a vertically split container as the base container of\r
+a workspace. Since the split mode is a property of the workspace, it will not be\r
+stored. In this case, you will have to manually wrap your layout in such a\r
+container:</p></div>\r

+<div class="paragraph"><p>If you use the <tt>title</tt> attribute to match a window and find that it doesn’t\r
+work or only works sometimes, the reason might be that the application sets the\r
+title only after making the window visible. This will be especially true for\r
+programs running inside terminal emulators, e.g., <tt>urxvt -e irssi</tt> when\r
+matching on <tt>title: "irssi"</tt>.</p></div>\r
+<div class="paragraph"><p>One way to deal with this is to not rely on the title, but instead use, e.g.,\r
+the <tt>instance</tt> attribute and running the program to set this window instance to\r
+that value:</p></div>\r
