| - | <hardprocess> | + | * Optional substructure in <event> block: defining a XML tag for each collection of reconstructed objects. When detector fast-simulation is applied, several configurations can be applied (for instance for lepton isolation) and several collection of the same object kind can be produced. The <event>-block substructure is designed to handle several collections of a same object kind. Example: |

| - | * List of relevant observables for each object collection must be defined. | + | Warning: If the LHE file supplies several collections of jets, people must obviously use only collection of jets in their analysis. |
