Не работают параметры в ngx http xslt module

[kotz]

nginx version: nginx/0.8.53

location / {
         root /vhosts/htdocs;
         xslt_stylesheet /vhosts/xml/files.xsl   uuids='test';
}

При запросе вылитает 500-я, в error логе:
XPath error : Unfinished literal
runtime error
Evaluating user parameter uuids failed
2011/07/04 17:37:59 [error] 26531#0: *1 xsltSaveResultToString()
returned zero-length result while sending response to client, client:
195.*, server: dev, request: "GET /result.xml HTTP/1.1", host: "dev"
2011/07/04 17:39:40 [error] 26531#0: *2 invalid libxslt parameter
"uuids" while sending response to client, client: 195.*, server: dev,
request: "GET /result.xml HTTP/1.1", host: "dev"

Если параметр не используется
преобразование работает...

Спасибо
