What steps will reproduce the problem?

Take a simple .properties file (attached):
key1=This is value 1.
key2=This is value 2.

Convert to xlf using okf_properties-html-subfilter.

The result contains duplicated Ids (in this case tu1, attached)

This is not correct, according to the XLIFF spec:

"The required id attribute is used to uniquely identify the within all and elements within the same ."
