When using the CSS length property value of '0', e.g. in margin-top="0", FOP produces an error: ERROR (PropertyList.java:365) [org.apache.fop.fo.PropertyList] No conversion defined 0; property:'margin-top' Bu the CSS specs state: After the '0' length, the unit identifier is optional. FOP should accept the length '0' and use a default unit.
In XSL-FO <length> values must have a unit qualification. See section 5.11 of the XSL-FO specification.
