Here I'm wondering whether the nested list could just be merged
into the primary item (and I'd omit the colon before "enables").

"a union".  English can be tricky for us non-native speakers at 
times, since usually you would use "an" before "u", except when 
that "u" is pronounced as a consonant or a syllable starting with 
one.  And the "u" in "union" actually is prounced as "you-nion".
