[libvirt] xml style?

[Eric Blake]

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?
