After conversion from dsl to diсtd format appear HTML tags:
<k>...</k>, <blockquote>...</blockquote>, <kref>...</kref>
This formatting is not part of the DICT standard. I think for DICT format it is better, that was PlainText without these elements of formatting.
It is better the HTML tags <kref>...</kref> to replace with format codes {...}, and all other tags to remove.
The above is true for other directions of conversion. For example, from stardict to dictd and from xdxf to dictd.
