6 | * TODO: |
7 | * |
8 | * - I'm never entirely convinced that having a fragment link to |
9 | * come in at the start of the real text in the file is |
10 | * sensible. Perhaps for the topmost section in the file, no |
11 | * fragment should be used? (Though it should probably still be |
12 | * _there_ even if unused.) |
13 | * |
14 | * - new configurability: |
15 | * * a few new things explicitly labelled as `FIXME: |
16 | * configurable' or similar. |
17 | * * HTML flavour. |
18 | * * Some means of specifying the distinction between |
19 | * restrict-charset and output-charset. It seems to me that |
20 | * `html-charset' is output-charset, and that |
21 | * restrict-charset usually wants to be either output-charset |
22 | * or UTF-8 (the latter indicating that any Unicode character |
23 | * is fair game and it will be specified using &#foo; if it |
24 | * isn't in output-charset). However, since XHTML defaults to |
25 | * UTF-8 and it's fiddly to tell it otherwise, it's just |
26 | * possible that some user may need to set restrict-charset |
27 | * to their charset of choice while leaving _output_-charset |
28 | * at UTF-8. Figure out some configuration, and apply it. |
29 | * |
30 | * - test all HTML flavours and ensure they validate sensibly. Fix |
31 | * remaining confusion issues such as <?xml?> and obsoleteness |
32 | * of <a name>. |
33 | * |
34 | * - proper naming of all fragment IDs. The ones for sections are |
35 | * fine; the ones for numbered list and bibliociteds are utter |
36 | * crap; the ones for indexes _might_ do but it might be worth |
37 | * giving some thought to how to do them better. |
78c73085 |
38 | * |
3e82de8f |
39 | * - nonbreaking spaces. |
40 | * |
41 | * - free up all the data we have allocated while running this |
42 | * backend. |
