+
+The default location where xmllint will look for the catalog file is

+
+  foo bar baz.      [3]

+Subject: too many margin numbers
+Date: Sun, 13 Apr 2014 12:28:14 +0200
+Package: sisu
+Version: 5.3.4-1
+Severity: wishlist
+
+when using the following code:
+
+foo bar.
+
+code{
+
+  baz
+
+}code
+
+foo bar baz.
+
+the result in the output (pdf) is:
+

+baz               [3]

+foo bar baz.      [5]
+
+the '[n]' designates the margin number at the right site of the page.
+
+the problem is that sisu gives margin numbers to *empty* lines, which is
+wrong. margin numbers should only be assigned to actual content.
+
+Regards,
+Daniel
+
+***** NOTES/COMMENTS
+
+issue with pdf, look again, consider,
+this is cosmetic, a fix should be found, but is not striaghtforward
+alignment issue for code blocks not so easy to fix in some outputs, have so far ignored
+this is an issue with other types of text block as well
+
+reason why this has not been addressed especially with code blocks:
+the easiest fix would be to place the numbering at the end of the first line of a code block
+however, as it is now, if you copy & paste a block of code you should get the code
+if numbering is moved down to the first line, a copy of the code block will inlcude the
+extraneous (to the code) object number
+which is to my mind a bigger problem
+
+That said re pdf, LaTeX XeTeX are flexible, it may be possible to drop the ocn
+at the start of a code block lower on its line so that it is closer to the code
+that follows

+
+monospace for url outputs in pdf
+
+this is default behavior of the latex url package (it uses tt typewriter font)
+it is possible to modify the font to sf class or tm/rm class, & I now default to sf
+this means when the sisu default sf is used there will be no difference in typeface,
+but when times roman or other is used, urls will be in sf instead of that font,
+(instead of the latex default typewriter)
+
+it provides a visual cue even when output is monochrome, without color
+(and is in some way related to #744391 sisu output: no color on a4 portrait)
+however, it is worth noting here that urls are printed in a smaller font so as

+The idea of recursive includes is un-attractive (messy for a document)
+
+.ssm currently can contain .sst or .ssi
+.sst files can be processed independently,
+.ssi files are only insertions & cannot
+
+allowing .ssi to also include other .ssi or .sst could lead to recursive .ssi
+allowing .ssm to also include other .ssm .ssi or .sst could lead to recursive .ssm
+
+stopping after an additional level of includes seems arbitrary, and possibly prone to error if you are dealing with many documents
+
+a possibility would be to have another file extension to flag the role of the file,
+.ssmi (not very attractive) might do it
+(providing visual cue signalling its role as both a master file and an insertion/included file that cannot be processed independently)
+a .ssmi file must be included in a .ssm file

+
+first, if you have an url within @creator, like:
+
+  @creator: foo bar http://example.org
+
+the generation fails (pdf output).
+
+as a workaround, i put the url into parenthesis, like:
+
+  @creator: foo bar (http://example.org)
+
+but then, it would be nice if that url would be automatically
+transformed into a link in the output format (pdf).

+
+if a line within a 'code{...}code' block is longer and needs to be
+wrapped, sisu indicates the wrapping with an 'arrow' (←) symbol, which
+is nice.
+
+it would be even nicer if the arrow would not 'selectable', so that when
+you mark the line spanning over two lines with your mouse, the arrow is
+not selected and thus not copy&pasted.
+
+i don't know how to do this, but it's possible within pdfs, as can be
+seen in lots of pdfs in the internet.

+
+if you have a '(C)' in :copyright:, it is automatically replaced with a
+copyright symbol, which is nice, however, it sisu does that with the
+first occurence only.
+
+so if you use:
+
+ :copyright: (C) john doe<br />(C) jane doe
+
+then the second occurence is not replaced and that combination looks
+very ugly. i suggest you replace all occurences of '(C)' to the
+copyright symbol automatically.
