Case Insensitive Search in XPath 1.0

[Kingspice]

Hi,
I want to do a Xpath query e.g.:
<xsl:for-each select="/library/authors/author[contains(lastname,$author)]">
but want it to be a case-insensitive. I know in Xpath 2.0 there is a lower-case function but is there anyway of achieving the same desired effect using Xpath 1.0?

Thanks
Gareth
