According to the DITA 1.3 specification, the <lines> element represents

However, XMLmind XML Editor (XXE) renders white space as significant.
And when ditac (dita converter) converts <lines> to HTML, the result is
that white space, again, is treated as significant.
It could very well be that the interpretation of ditac and XXE makes
more sense for the use cases that <lines> are meant for,
but I would
nevertheless bring this to your attention and ask for a clarification.
Sorry but we don't know how to implement “text where line breaks are
significant but white space is not”. So this is really a limitation of
XMLmind XML Editor (XXE) and XMLmind DITA Converter (ditac).
