Re: p:filter using p:with-option for select

Thanks Martin, that works.

I'm used to using XPath expressions within select attribute on 
p:with-option, to arrive at the value I wish to supply, but hadn't 
noticed that when the expected data type of that option is an 
XPathExpression or XSLTSelectionPattern, it needs to be a string (as 
explained in Standard Step Library § 1. Introduction). Probably because 
when the syntactic shortcut is used to supply the option value via an 
attribute, the quotes aren't required (as explained in An XML Pipeline 
Language § 16.4.3.1. Syntactic Shortcut for Option Values).

Another lesson learned :)

Kind regards,

Sheila
