The Solaris Linker and Libraries Guide can serve as a reference if the official ELF spec is missing something that we agree upon, but for the SHN_LORESERVE thing you can just quote http://www.sco.com/developers/gabi/latest/ch4.eheader.html :

> e_shnum
>  ...
>  If the number of sections is greater than or equal to SHN_LORESERVE (0xff00), this member has the value zero and the actual number of section header table entries is contained in the sh_size field of the section header at index 0. (Otherwise, the sh_size member of the initial entry contains 0.)



> e_shstrndx
>  ...
>  If the section name string table section index is greater than or equal to SHN_LORESERVE (0xff00), this member has the value SHN_XINDEX (0xffff) and the actual index of the section name string table section is contained in the sh_link field of the section header at index 0. (Otherwise, the sh_link member of the initial entry contains 0.)
