Hi all

I have a question about csv:serialize and blank nodes. Trailing blanks are indicated with a separator, but those in the middle are. 

     csv:serialize(
     <rows>
        <row> <f>1</f> <s>2</s> <t>3</t></row>
        <row> <f></f>  <s></s>  <t>3</t></row>
        <row> <f>1</f> <s></s>  <t>3</t></row>
        <row> <f>1</f> <s></s>  <t></t></row>
        <row> <f>1</f> <s>2</s> <t></t></row>
     </rows>)

Here is the output (BaseX 7.8.1) , where line 4 and 5 are missing trailing separators:

1,2,3
,,3
1,,3
1
1,2

Could this be fixed, or is it a feature?

All the best
