Debugging xmlroff
Command Line

-d2 command line switch dumps FO tree

Each node shows its type [FoTree], its address [0x82a0698], and its reference count [1].
Values of the node's properties (GObject properties, which mostly correspond to XSL properties) are shown indented underneath the node information.
Properties of the node's parent type (and that type's parent type, etc.) are shown indented relative to the properties of the node's type.
