Just to expand on Jim's reply, TL9000 is one of many "ISO based" standards that include ISO9001 in its entirety. TL9000, AS9100, TS16949, etc. are all ISO9001 with a bunch of industry specific stuff added to it.
I'm not positive about TL9000 because I've not read it, but in AS9100 and TS16949, the ISO text is regular text - the additional industry specific requirements are in bold italic font.
