Re: [libvirt] xml style?

When writing an attribute in xml, which style is preferred? <element attr='single'/> <element attr="double"/> We are currently rather split-brain in libvirt, among three general areas: test programs under tests/*data/*, documentation under docs/*.html.in, and RNG schemas under docs/schemas/*. In all cases, both styles are present, but in different proportions: $ git grep '="' tests/*data |wc 48 163 4276 $ git grep "='" tests/*data |wc 5994 21336 526402 $ git grep '="' docs/schemas/ |wc 1522 4599 103050 $ git grep "='" docs/schemas/ |wc 566 1699 33005 $ git grep '="' docs/*.in |wc 1288 6436 114146 $ git grep "='" docs/*.in |wc 611 2242 42950 Is it worth a cleanup patch that settles on one particular style, or even a syntax check that forces style compliance?
