Comment:

 Patch fixes is for me. Logic is as follows:

 - According to the spec, the `<value>` tag can either contain a subtag
 which specifies the data type, or can contain a string. As it was, the
 parser would only handle non-empty strings so supplying `<value></value>`
 would cause it to just ignore the whole node.

 - My patch adds a tracking variable so we know when we reach the end of a
 `<value>` element whether it contained a sub-tag. If it didn't, we just
 use the contents of the `<value>` tag itself - empty or otherwise. Now the
 struct provided in comment:7 works.

 PS Devs - what is the policy on modifying external libraries? I've
 reported the bug with Incutio in the hope they might address it in a
 future version, no response yet.
