And to be safe in XSLT 3 in any context you probably want

<xsl:param name="pattern"
as="xs:string"
expand-text="no">\{\{image_[^}]+\}\}([^{]+)\{\{/image\}\}</xsl:param>


otherwise the use of expand-text="yes" higher up the tree causes the
same problem you run in with using the regular expression in the attribute.
