format whose speci fic at i on is available to the general pub l ic , that is suitable for revising
the document straightfor wardly with ge ne ri c text editors or (for images composed of pixels)

suitable for input t o text formatters. A copy made in an ot h er wi se Transparent file format
whose markup, or absence of markup, has been arranged to thwart or discourage subsequent
modification by readers is not Transparent. An image format is not Transparent if used for
any s ub st antial amount of text. A c opy that is not “Tran sp ar ent” is called “Opaqu e”.
Examples of suitable formats for Transparent copies include plain ASCII without markup,
Texinfo input format, LaT

and standard-conforming simple HTML, PostScrip t or PDF designed for human modifi-
cation. Examples of transparent image formats inc l ud e PNG, XCF and JPG. Opaque
formats include proprietar y formats that can b e read and edited only by proprietary word
processors, SGML or XML f or which th e DTD and/or process i ng tools are not generally
available, and the machine-generated HTML, PostScript or PDF produced by some word
processors for output purposes only.

Title” of such a section when you modify the Docu me nt means that it remains a section
“Entitled XYZ” according to this definition.
