Hi,
Yes, location="Server." should work but as you noticed, it’s not perfect as it could match other paths. In other words, right now the documents macro doesn’t really have a way to list only children. It lists all page matching the passed location.
There’s Children Macro (XWiki.org) but it’s a tree, not a table.
As as a workaround FTM you could check Parentschildrenlivetable displays nothing - #21 by vmassol and below.
