These are the section type and attributes fields. A MachO section can have only one Type, but can have any of the attributes specified.

S_REGULAR - Regular section.

S_ZEROFILL - Zero fill on demand section.

S_CSTRING_LITERALS - Section with literal C strings.

S_4BYTE_LITERALS - Section with 4 byte literals.

S_8BYTE_LITERALS - Section with 8 byte literals.

S_LITERAL_POINTERS - Section with pointers to literals.

S_NON_LAZY_SYMBOL_POINTERS - Section with non-lazy symbol pointers.

S_LAZY_SYMBOL_POINTERS - Section with lazy symbol pointers.

S_SYMBOL_STUBS - Section with symbol stubs, byte size of stub in the Reserved2 field.

S_MOD_INIT_FUNC_POINTERS - Section with only function pointers for initialization.

S_MOD_TERM_FUNC_POINTERS - Section with only function pointers for termination.

S_COALESCED - Section contains symbols that are to be coalesced.

S_GB_ZEROFILL - Zero fill on demand section (that can be larger than 4 gigabytes).

S_INTERPOSING - Section with only pairs of function pointers for interposing.

S_16BYTE_LITERALS - Section with only 16 byte literals.

S_DTRACE_DOF - Section contains DTrace Object Format.

S_LAZY_DYLIB_SYMBOL_POINTERS - Section with lazy symbol pointers to lazy loaded dylibs.

S_THREAD_LOCAL_REGULAR - Section with ....

S_THREAD_LOCAL_ZEROFILL - Thread local zerofill section.

S_THREAD_LOCAL_VARIABLES - Section with thread local variable structure data.

S_THREAD_LOCAL_VARIABLE_POINTERS - Section with ....

S_THREAD_LOCAL_INIT_FUNCTION_POINTERS - Section with thread local variable initialization pointers to functions.

S_ATTR_PURE_INSTRUCTIONS - Section contains only true machine instructions.

S_ATTR_NO_TOC - Section contains coalesced symbols that are not to be in a ranlib table of contents.

S_ATTR_STRIP_STATIC_SYMS - Ok to strip static symbols in this section in files with the MY_DYLDLINK flag.

S_ATTR_NO_DEAD_STRIP - No dead stripping.

S_ATTR_LIVE_SUPPORT - Blocks are live if they reference live blocks.

S_ATTR_SELF_MODIFYING_CODE - Used with i386 code stubs written on by dyld.

S_ATTR_DEBUG - A debug section.

S_ATTR_SOME_INSTRUCTIONS - Section contains some machine instructions.

S_ATTR_EXT_RELOC - Section has external relocation entries.

S_ATTR_LOC_RELOC - Section has local relocation entries.

ParseSectionSpecifier - Parse the section specifier indicated by "Spec". This is a string that can appear after a .section directive in a mach-o flavored .s file. If successful, this fills in the specified Out parameters and returns an empty string. When an invalid section specifier is present, this returns a string indicating the problem. If no TAA was parsed, TAA is not altered, and TAAWasSet becomes false.
