-.Ss XML Filter
-The XML filter, specified by
-.Fl f Ar xml ,
-is the default filter.  This filter has no additional arguments.
 .Pp
-The XML filter creates an XML document where element names are their respective
-roff macro names.  Each element name has an associated
-namespace, which is one of 
-.Dq block ,
-.Dq head ,
-.Dq body ,
-or
-.Dq inline ,
-corresponding to the display mode of a node.  The document root is
-always the
-.Dq mdoc
-element, in the default namespace; the 
-.Dq head
-namespace is for block headers (such as 
-.Sq .Ss
-and
-.Sq .Sh ) ;
-the
-.Dq body
-namespace is for block bodies; and the
-.Dq inline
-namespace is for in-line elements (such as
-.Sq .Em ) .
-.Ss HTML Filter

-Most caveats of

-stem from ambiguities in 
-.Xr mdoc 7
-or the necessary limitations of converting an ad hoc language into
-structured ones:
-.Bl -enum -compact -offset indent
-.It 
-The engine doesn't understand the
-.Sq \&No ,
-.Sq \&Db ,
-.Sq \&Xc ,
-and
-.Sq \&Xo
-mdoc macros.
-.It 
-All macro arguments may be quoted, instead of only some.
-.It 
-Blank lines raise errors.
-.It 
-If terminating punctuation is found, then 
-.Em all
-remaining tokens are flushed after line scope is closed, not just the
-last one.
-.El
-.Pp
-The roff engine in 
-.Nm
-produces text in-line; thus, output may already be partially written by
-the time an error is encountered.
