MIF Filter: consequential Strings in XRefs must be merged with hard return symbols or left as they are
All consequential String statements in ParaLine are merged into a single String. However, ParaLine > XRef > String statements are rendered differently - as if there were hard returns between them:

ParaLine > XRef parts:
<XRef
<XRefName `Heading & Page'>
<XRefSrcText `81299: Body: Para 2.'>
<XRefSrcIsElem No>
<XRefSrcFile `'>
<XRefLastUpdate 1591177988 872000>
<XRefSrcElemNonUniqueId `'>
<XRefAltText `'>
<XRefApiClient
<XRefClientName `'>
<XRefClientType `'>
> # end of XRefApiClient
<Unique 998449>
> # end of XRef
<String ` Refer to“'>
<String `Para 2.'>
<String `” <{Emphasis}\> page -1 : 1 '>
...
<XRefEnd >
Thus, the mentioned Strings are merged on writing back a translation and the look and feel of the document is changed.
