It seems to be objecting to the space between the start tag and end tag of
xsl:variable.

It's wrong to object to it: whitespace in this position should be stripped
and ignored.

But it's more conventional, if your xsl:variable has a select attribute, to
write

<xsl:variable name="link" select="file_link"/>
