Not to answer the question, but just to add to it; from the XML 1.1 spec 
<https://www.w3.org/TR/2006/REC-xml11-20060816/#sec-xml11>:

    In addition, XML 1.0 attempts to adapt to the line-end conventions
    of various modern operating systems, but discriminates against the
    conventions used on IBM and IBM-compatible mainframes. As a
    result, XML documents on mainframes are not plain text files
    according to the local conventions. XML 1.0 documents generated on
    mainframes must either violate the local line-end conventions, or
    employ otherwise unnecessary translation phases before parsing and
    after generation. Allowing straightforward interoperability is
    particularly important when data stores are shared between
    mainframe and non-mainframe systems (as opposed to being copied
    from one to the other). Therefore XML 1.1 adds NEL (#x85) to the
    list of line-end characters. For completeness, the Unicode line
    separator character, #x2028, is also supported.
