关于信用证47A条款的问题，谁知道这是什么意思么？

In the event of discrepant documents being presented to us under this credit and if we give notice of refusal under the relevant provision of ucp-600,we shall however retain the right to accept a waiver of discrepancies from the applicant provided that no written instructions to the contrary have been received by us from the presenter before the release of documents.Documents containing discrepancy(ies)will be subject to deduction of discrepancy fee of USD50/-plus swift charges USD35/or equivalent form the proceeds subject to acceptance of documents.

翻译如下：
若我方依据UCP600相关规定对该信用证下的提交的不符单据发出拒付通知，在释放单据前我方没有收到来自交单人的书面的相反指示，我方将保留接受来自申请人放弃不符点的权利。
包含不符点的单据将从信用证款里扣除USD50加SWIFT 费USD35 或者相等的费用。


其实就是两点：
1. 如果存在不符点，且交单人没有明确要求撤单， 银行有权接受申请人放弃不符点的指示。 
2. 如果银行接受单据，存在的不符点将扣费。

特殊条款： 1. 所有单据除发票外必须由英文签发 2. 严格机制提交多份信用证单据 3. 所有单据必须体现信用证号    + 关于海运单据，必须注明承运船舶的imo号    +运输的公司如果受到美国、欧盟、联合国限制是被禁止的
