NIFI-7493 - fix checkstyle issue
> XML Schema Inference can infer a type of String when it should be Record
> ------------------------------------------------------------------------

> Key: NIFI-7493

> From the mailing list:
> {quote}I have configured a XMLReader to use the Infer Schema. The other issue
> is that I have problems converting sub records. My records looks something
> like this:<RootLabel> <Part1> <name>John Doe</name>
> <adress>some there</adress> </Part1> <Part2>
> <Job>workingman</Job> </Part2> <Part3> <Details>
> <additionalInfo name="Location">New York</additionalInfo>
> <additionalInfo name="Company">A Company</additionalInfo>
> </Details>
> </Part3>
> </RootLabel>
>
> The issues are with the subrecords in part 3. I have configured the XMLReader
> property "Field Name for Content" = value
>
> When the data is being converted via a XMLWriter the output for the
> additionalInfo fields looks like this:
> <Part3> <Details> <additionalInfo>MapRecord[\{name=Location,
> value=New York}]</additionalInfo>
> <additionalInfo>MapRecord[\{name=Company, value=A
> Company}]</additionalInfo> </Details>
> </Part3>
>
>
> If I use a JSONWriter I gets this:
> "Part3": { "Details": {
> "additionalInfo": [ "MapRecord[\{name=Location, value=New York}]",
> "MapRecord[\{name=Company, value=A Company}]" ]
> }
> }{quote}
> The issue appears to be that "additionalInfo" is being inferred as a String,
> but the XML Reader is returning a Record.
>
> This is probably because the "additionalInfo" element contains String
> content and no child nodes. However, it does have attributes. As a result,
> the XML Reader will return a Record. I'm guessing that attributes are not
> taken into account in the schema inference, though, and since
> "additionalInfo" has no child nodes but has textual content, it must be a
> String.
