If the VR is unknown (for example, if a private element), then process_unknown_VR is used to determine whether to replace or not. process_unknown_VRs: bool, optional If True (default) then attempt the fix even if the VR is not known. Returns ------- No return value. However, the callback function will return either the original RawDataElement instance, or a fixed one. rrr N)r"rdata_element_callbackdata_element_callback_kwargsr&r r r! fix_separator5s  r)c Ksv|jdur|Sz t|j|W|Sty:|dD]}zt||Wn ty/Yqw|j|d}qY|Sw)Nwith_VRsr)rr convert_value ValueErrorr)r r rr r r!fix_mismatch_callbackVs   r-r*cCstt_d|it_dS)a%A callback function to check that RawDataElements are translatable with their provided VRs.
