Ian Beaumont commented on XALANJ-2547:
--------------------------------------
My understanding is that the CDATA data should not be changed. According to
this
http://www.w3.org/TR/REC-xml/#sec-line-ends
only "parsed entities" should have the line breaks changed and don't CDATA
sections contain "unparsed character data"?

> Project: XalanJ2
> Issue Type: Bug
> Security Level: No security risk; visible to anyone(Ordinary problems in
> Xalan projects. Anybody can view the issue.)
> Components: transformation
> Affects Versions: 2.7.1
> Environment: Windows 7 64
> Reporter: Daniel Schwering
> Priority: Minor
> Labels: newbie
>
> When I have a Windows Line Break (CR+LF) in a CDATA section, the transformer
> turns it into (CR+CR+LF), which most editors display as an extra blank line.
