12 | - The docbook stylesheet injects empty anchor tags into generated HTML, identified by an auto-generated ID. | |
13 | - Ask the docbook stylesheet to generate reproducible output when generating (these) ID values. | |
14 | - This makes the output of this stylesheet reproducible across identical invocations on the same input, | |
15 | - which is an easy and significant win for achieving reproducible builds. | |
16 | - | |
17 | - It may be even better to strip the empty anchors from the document output in addition to turning on consistent IDs, | |
18 | - for this stylesheet contains its own custom ID logic (for generating permalinks) already. | |
