The HTML generated for EPUB is XHTML conformant, UTF-8 encoded, and
formatted without the usual HTML navigation headers and footers.
Most of these features are enabled with customization variables, such as
USE_XML_SYNTAX
or OUTPUT_FILE_NAME_ENCODING
. Some
features of printed output are used in EPUB. In particular, the Top
node does not appear in the EPUB output, while a title page is
generated. This is obtained by setting NO_TOP_NODE_OUTPUT
.
The OUTFILE
and SUBDIR
customization variables values
correspond initially to the EPUB directory container and/or the
EPUB output file (see Container Directory and Output Files). These
customization variables values are undefined or reset to the
locations in the container directory where the XHTML files are output
for the HTML generation. It is mentioned here because resetting
customization variables is unusual; however, the variables reset are
used internally for the conversion, and should not interact with any
customization set by the user.
