xpath express does not support some special character? [message #507352]

I use xml data source, and define a dataset with following "Row mapping":
/REPORT/OBJECT-SUMMARY[@name="{?param_1?}"]/AP
while the param_1 = "[bedred]mx", then the total xpath is:
/REPORT/OBJECT-SUMMARY[@name="[bedred]mx"]/AP

It can not work. and get following exception:
Data Section:
+ Cannot execute the statement.
The filter definition is invalid.
I have verified in "xml spy", the above xpath is a valid xpath expression.

It seems that birt can not support some special character. Is there any workaround for this.
