A lot of my stylesheets start with entity declarations for cr (&#x0A; and in
some cases &#x0D;&#x0A;) and crt (<xsl:text>&cr;</xsl:text>), so I can write

<xsl:text>abc</xsl:text>&crt;

See for an example [1].

This also works with XSLT 1.0.

Note that &cr; will not work within attributes because of attribute-value
normalization, a step every XML parser has to  pass during parsing of the
stylesheet [2]. A workaround is a $newline variable as described by Liam.
