ProgrammingThis forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

The ePub standard requires xhtml 1.1 per the specification.
XHTML 1.1 starts the chapter.xhtml page to define the type with:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html
PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
In the OPF file, the extension which matches the MIME type is being given:
Code:
.xhtml is for application/xhtml+xml documents
.html is for text/html documents
For instance, ePub3 requires .xhtml!!
It is strongly suggested that you use the .xhtml extension for all EPUB content documents. Browsers will not interpret HTML content as application/xhtml+xml without that extension.
Despite that it is impossible to use HTML into an EPUB, can we in future get EPUB be used with HTML with or instead of XHTML ?
Generally, XHTML is upward-compatible with HTML but more precise. You should specify XHTML in order to have maximum control over what any particular device will do with the content. (Don't forget the original black-and-white Amazon Kindles: they're still out there.)

and the otherway around too. Non Kindles do not understand Kindle format. Try gutenberg.org with kindles, good luck.
It is a flame war kindle vs epub Anyhow, those are "proprietary" formats.
Could GNU make some a format for epub neutral and clean. Even if GNU would make one, it will never be used by proprietary, eager, money-driven giant informatics corporation (e.g. amazon).
