[Basic] Shield Penetration

[VariousRen]

Pg. 484 includes rules for damage to shields, and states that "Damage in excess of cover DR penetrates the shield and possibly injures [the target]" and then points to the rules for over penetration. The general over penetration rules on page 408 say that a piercing, impaling, or tight beam burning ranged attack can over penetrate (leaving out crushing and cutting)

The phrasing of the shield damage rules and the fact that the general overpen rules only talk about range attacks make me wonder if crushing and cutting attacks are allowed to penetrate shields to hit the person behind them. It seems to me that a sword blow should be able to cut through a light shield into the actual target, but I'm not sure if this is the intention
