Section 3.1, 4.1 says:

a)  Section 3.1, explanation of maskGenAlgorithm, last paragraph
    (2nd paragraph on page 9)

b)  Section 4.1, explanation of maskGenFunc, last paragraph
    (2nd paragraph on page 11)
 
both say:

         Although mfg1SHA1Identifier is defined as the default value for
         this field, implementations MUST accept both the default value
         encoding (i.e., an absent field) and mfg1SHA1Identifier to be
         explicitly present in the encoding.

It should say:

both a) and b) should say:

         Although mgf1SHA1Identifier is defined as the default value for
         this field, implementations MUST accept both the default value
         encoding (i.e., an absent field) and mgf1SHA1Identifier to be
         explicitly present in the encoding.

Notes:

Rationale: 4 instances of the same character twister:

mfg1SHA1Identifier
--- ^^
mgf1SHA1Identifier

Note: "MGF" is the abbreviation of "Mask Generation Function".
