An element has two attributes: type and label. The following types are valid: point, vector, line, segment, conic, numeric, angle.
<element
type="line" label="a">
<show object="true"
label="true"/>
<objColor r="0"
g="0" b="255"/>
<lineStyle thickness="2"
type="0"/>
<eqnStyle
style="implicit"/>
<coords x="6.0"
y="7.8" z="1.0"/>
</element>

where type is an integer representing one of
the following dashing styles:

10 |
LINE_TYPE_DASHED_SHORT |

LINE_TYPE_DASHED_LONG |

For an element of type line attribute style may have values explicit, implicit or parametric. For parametric the second attribute parameter specifies the parameter's name.
For an element of type conic attribute style may have values implicit or specific.
