XML parsers normalize CR+LF to LF, except in attribute values containing a CR written as a numeric character reference like
get only LFs () 99.999% of the time.

To better understand what is going on, you should use something that helps you
create a more tangible representation of the XPath/XSLT node tree.
XPath tree visualization stylesheets you can apply to the above XML: http://skew.org/xml/stylesheets/treeview/ascii/ http://skew.org/xml/stylesheets/treeview/html/ http://www.cranesoftwrights.com/resources/showtree/
Software providing XPath tree visualization: http://www.topxml.com/xpathvisualizer/ http://www.logilab.org/xpathvis/ and various XML editors like XML SPY.
In the case of the element named 'attr', its child text node will encapsulate the text (linefeed character) + 'value' no matter what you do, because it is considered signficant in the XPath data model.
If you don't wish to use this text verbatim, you may find that applying the XPath function normalize-space() to the node or string will give you the string you wanted. The normalize-space function takes the "string-value" of its argument, strips leading and trailing whitespace, and collapses intermediate runs of whitespace to a single space character, returning an XPath string object.
