#IF parser function
{{#show:Albania/OER| ?Has capital|link=none}} yields Tirana
{{#show:Hungary | ?In OECD}} yields "true"
{{#show:Brazil| ?In OECD}} yields ""
{{#if:string | yes | no}} yields "yes"
{{#if:{{#show:Brazil| ?In OECD}}| yes | no}} yields "no"
{{#if:{{#show:France| ?In OECD}}| yes | no}} yields "yes"
Thus:
{{#if:{{#show:Brazil| ?In OECD}}|Category:OECD|}} yields ""
{{#if:{{#show:France| ?In OECD}}|Category:OECD|}} yields "Category:OECD"
Thus:
[[{{#if:{{#show:France| ?In OECD}}|Category:OECD|}}]] yields ""
But the [[ ]] codes do not make it a valid category definition.
What about
{{#if:{{#show:France| ?In OECD}}|[[:Category:OECD]]|}} yields "Category:OECD"
