[xslt] string literal with single-quote inside won't parse

[Viktor Štujber <theultramage gmail com>]

Hello. I noticed that libxslt errors out if I try to use a
single-quoted string literal with a single-qoute (') or ' inside
it. I know it can be worked around using a temporary variable to store
the literal, however I'm curious whether this issue will be resolved
someday, or whether it is 'a feature'.

For reference, the xpath document on the w3c site says in its
introduction, "To avoid a quotation mark in an expression being
interpreted by the XML processor as terminating the attribute value
the quotation mark can be entered as a character
reference (" or ')".

<xsl:template match="/">
	<xsl:value-of select="'Hello, I&apos;m a literal with an apostrophe inside.'"/>
</xsl:template>
