|CDX Constant Name:||kCDXProp_Frag_ConnectionOrder|
|CDX Constant Value:||0x0505|
|Property of objects:||kCDXObj_Fragment|
|First written/read in:||ChemDraw 4.0 / 6.0|
An ordered list of attachment points within a fragment.
Used, for example, to ensure that a fragment is connected in the right head-to-tail order to whatever object contains it. The list of attachment points (that is, Nodes with a kCDXProp_Node_Type of ExternalConnectionPoint) contained by this property is in the same order as the corresponding list of bonds stored in the containing Node's kCDXProp_Atom_BondOrdering property.
This property is meaningless for fragments that contain fewer that two attachment points, and should not be present in those cases.
If this property is absent:
The ordering of attachment points in this fragment is not considered to be significant (or there are fewer than two attachment points).
