b24e4bec819b29f1ec8e77083d4e7610c5dd9c77Lukas Slebodnik - The docbook stylesheet injects empty anchor tags into generated HTML, identified by an auto-generated ID.
b24e4bec819b29f1ec8e77083d4e7610c5dd9c77Lukas Slebodnik - Ask the docbook stylesheet to generate reproducible output when generating (these) ID values.
b24e4bec819b29f1ec8e77083d4e7610c5dd9c77Lukas Slebodnik - This makes the output of this stylesheet reproducible across identical invocations on the same input,
b24e4bec819b29f1ec8e77083d4e7610c5dd9c77Lukas Slebodnik - which is an easy and significant win for achieving reproducible builds.
b24e4bec819b29f1ec8e77083d4e7610c5dd9c77Lukas Slebodnik -
b24e4bec819b29f1ec8e77083d4e7610c5dd9c77Lukas Slebodnik - It may be even better to strip the empty anchors from the document output in addition to turning on consistent IDs,
b24e4bec819b29f1ec8e77083d4e7610c5dd9c77Lukas Slebodnik - for this stylesheet contains its own custom ID logic (for generating permalinks) already.

<!--
- helper template to do conflict resolution between various headings with the same inferred ID attribute/tag from the headerlink template
- this conflict resolution is necessary to prevent malformed HTML output (multiple ID attributes with the same value)
- and it fixes xsltproc warnings during compilation of HTML man pages
-
- A simple top-to-bottom numbering scheme is implemented for nodes with the same ID value to derive unique ID values for HTML output.
- It uses two parameters:
templateID the proposed ID string to use which must be checked for conflicts
keyNode the context node which 'produced' the given templateID.
-
- Conflicts are detected solely based on keyNode, templateID is not taken into account for that purpose.
