9. Frame formats
9.1 General requirements
Change the paragraph as follows:
The format of the MAC frames is specified in this clause. WUR frame format is defined in Subclause 9.10, and other MAC frame formats are defined in Subclauses 9.2 to 9.9. A STA shall be able to properly construct a subset of the frames specified in this clause for transmission and to decode a (potentially different) subset of the frames specified in this clause upon validation following reception. The particular subset of these frames that a STA constructs and decodes is determined by the functions supported by that particular STA. A STA shall be able to validate every received frame using the frame check sequence (FCS) and to interpret certain fields from the MAC headers of all frames.

A STA shall transmit frames using only the frame formats described in Clause 9.
