xsltproc and friends will happily generate the index in one
pass, obviating the need for the separate index.xml file, which
must be generated using the jade toolchain; thus commenting out
the (missing) external index and generating it on the fly;
N.B. there were only two </indexterm> entries in the document, but
at least they were present
The additional programs and content were stored in a directory called
ncurses_programs and were referred to in the document--the problem is that
only ./images/ were copied to the output tree, so HTML versions of the
document would fail in building AND the files would not be viewable.
Adjusted that be creating a ./resources/ directory along the same line
as the ./images/ directory. This can be changed, if desired, but this
allows for automated publication of the document. (Side benefit: this is
generalizable to all other TLDP documents.)
When generating a book (or article) index, the filename is index.sgml. Not an
issue with DocBook XML, only with the older tools which make several passes
over the input sources to create the index data (output as SGML in a file
called index.sgml) and then incorporate that into the final document.
removing extraneous and empty <author/>, non-validating <toc/>
replacing an <ulink/> with a mailto: with an <email/> element
stuffing an & in the url="" attribute value for a <ulink/>
document now validates
Though it is legal to define parameter entity substitutions in a
DTD's internal subset, you cannot actually use them there. It is only
legal to use a parameter entity substitution in an external subset.
See this:
https://www.w3.org/TR/1998/REC-xml-19980210#wfc-PEinInternalSubset
Therefore, for the XML-RPC-HOWTO, the %GoodStyleSheets; definition is
left uncommented, but the suppression of the alternate definition of
legal.notice is commented out.
Document validates and processes correctly, now, using the legal.notice
definition intended. N.B., there is no actual difference in the license
specified, just the markup used to communicate it.
The <emphasis/> tag cannot live inside a <systemitem/> or a <literal/>, but
it can certainly surround these elements; inverting to allow for validation
and processing.
first line of fdl.xml with XML text declaration was confusing xsltproc;
removed and things were fine, also removed commented out DOCTYPE declaration
used URI for DocBook 4.1.2 in system identifier in rpmupgrade.xml
commented out <xref endterm="xrefdemo" linked="xrefdemo" /> which was causing
a recursion error in the DocBook XSLT layer
document now validates and builds (except for PDF)
files were declared with <?xml version="1.0" encoding="UTF-8"?>
but were definitely not UTF-8; corrected and added Unicode BOM
Linux-Networking.xml: fixed a doubly-closed </ulink>
Overview.xml: there were several large pasted sections of text which
contained characters understood to be markup; wrapped the entire
sections in <![CDATA[ ]]> blocks;
Protocols-Standards-Services.xml: closing </sect1> tags cannot have id="" on
them: removed these; wrapped several email addresses with <email/> to allow
validation; fixed tons of URLs with proper <ulink/> elements; wrapped a few
pasted sections in <![CDATA[ ]]> blocks;
jade processor was very unhappy to have closing tags on <imagedata>;
removing them (which felt like violence) allowed the document to be
validated and processed
In his document build system, each script is cooked (wrapped in <![ CDATA []]>
during build process--this is elegant, but we are not calling his build
Makefile, so we need to store the cooked scripts in the source tree.
jade did not like trying to process <graphic/> elements where it could not
find the source images; also, it wanted the filename extension included (did
early DocBook SGML processing tools simply locate an image of the preferred
type?)
Commented out an <inlinemediaobject/> which was using processing instructions
(IGNORE/INCLUDE) to control selection of several <imageobject/> children and
one <textobject/> child; jade got confused because there was no <imageobject/>
being selected, only a <textobject/> so refused to process the document
Also, cleaned up some stray </listitem> and missing <emphasis> elements
throughout the document. Squashed one stray </chapter> ending the
bibliography and removed an attribute (title=) that was forbidden on a
<bibliography/> element.
The DOCTYPE specification was missing the System Identifier
"http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd"
Processing is still not validating properly, because the toolchain used to
generate this, before, created the index.xml file on a first pass, and then
the actual document on the second pass, in the style of SGML tools.
I would like to figure out how to support both with a processing instruction.
