I suggest to include at least the following extensions in the default list of extensions in dohtml: ico svg xhtml xml Multiple packages provide documentation with files with such extensions.
(In reply to comment #0) > ico .ico is not a widely recognizable image format. I suggest you replace it with something which standards accept.
16 packages on my system install *.ico files. These packages currently usually use doins. There might be more packages, which use dohtml, and silently fail to install *.ico files, which might be referenced by installed *.html files.
Certainly, adding extensions like svg would be nice. But I wonder if the advantages would outweigh the added complexity (e.g., devs must remember that dohtml changes behaviour when bumping an ebuild to EAPI 5). Also, it is easily possible to add further extensions with the -A option.
