> A comment in the ref guide got me looking at ConfigSolrXml.java and noticing that the parsing of solr.xml options here is very brittle and confusing.  In particular:
> * if a boolean option "foo" is expected along the lines of {{<bool name="foo">true</bool>}} it will silently ignore {{<str name="foo">true</str>}}
> * likewise for an int option {{<int name="bar">32</int>}} vs {{<str name="bar">32</str>}}
> ... this is inconsistent with the way solrconfig.xml is parsed.  In solrconfig.xml, the xml nodes are parsed into a NamedList, and the above options will work in either form, but an invalid value such as {{<bool name="foo">NOT A BOOLEAN</bool>}} will generate an error earlier (when parsing config) then {{<str name="foo">NOT A BOOLEAN</str>}} (attempt to parse the string as a bool the first time the config value is needed)
> In addition, i notice this really confusing line...
> {code}
>     propMap.put(CfgProp.SOLR_SHARESCHEMA, doSub("solr/str[@name='shareSchema']"));
> {code}
> "shareSchema" is used internally as a boolean option, but as written the parsing code will ignore it unless the user explicitly configures it as a {{<str/>}}
