Change:
common display. The basic wire format for names in the global DNS is a list of <del> labels with the root label last.  Each label is preceded by a length octet.  RFC1035 also defines a compression scheme that modifies this format. </del> <ins> labels ordered by decreasing distance from the root, with the root label last.  Each label is preceded by a length octet.  RFC1035 also defines a compression scheme that modifies this format. </ins> The presentation format for names in the global DNS is a list of <del> labels, encoded as ASCII, with the root label last, and a "." character between each label.  In presentation format, a fully- qualified domain name includes the root label and the associated separator dot.  In presentation format, a fully-qualified domain name with two additional labels is always shown as "example.tld." instead of "example.tld".  RFC1035 defines a method for showing octets that do not display in ASCII. </del> <ins> labels ordered by decreasing distance from the root, encoded as ASCII, with a "." character between each label.  In presentation format, a fully-qualified domain name includes the root label and the associated separator dot (for example, in presentation format, a fully-qualified domain name with two non-root labels is always shown as "example.tld." instead of "example.tld").  RFC1035 defines a method for showing octets that do not display in ASCII. </ins> The common display format is used in applications and free text. It is the same as the presentation format, but showing the root <del> label and the "." before it is optional and is rarely done.  In common display format, a fully-qualified domain name with two additional labels is usually shown as "example.tld" instead of "example.tld.".  Names in the common display format are normally written such that the first label in the ordered list is in the last position from the point of view of the directionality of the writing system (so, in both English and C the first label is the right-most label; but in Arabic it may be the left-most label, depending on local conventions). </del> <ins> label and the "." before it is optional and is rarely done (for example, in common display format, a fully-qualified domain name with two non-root labels is usually shown as "example.tld" instead of "example.tld.").  Names in the common display format are normally written such that the directionality of the writing system presents labels by decreasing distance from the root (so, in both English and C the first label in the ordered list is right-most; but in Arabic it may be left-most, depending on local conventions). </ins> Administration of names -- Administration is specified by delegation (see the definition of to "delegation" in zones).

Discussion:
Split into two pairs of commits (each first changing content and then line lengths) for easy partial acceptance, should that be desired: Improve grammar and diction Be consistent about ordering domain name labels from the root The second pair attempts to provide a consistent treatment of "domain name" as an abstract sequence of labels in directed graph order starting at the root, while maintaining clarity about wire, presentation, and common display formats rendering domain names in reverse.
