Problem with wfs_filter

Christian,

  You filter in your example is looking for an attribute name called 
"typ" and a value equal to "REFERENCE". In the gml you sent, I do not 
even see the attribute "typ".  Is your filer valid ?  All the filter 
encoding does is convert your filter to '[typ]' = '[REFERENCE]'.
If you think the filter is valid and should retun something, You could 
maybe send me your map and data and I can look into it.

Later,
