# curb_xml_extensions
Further extensions to format as generic XML, comma-separated, such as .xml or .runsettings.

## Values


| Value          | Notes                       |
|----------------|-----------------------------|
| `<extensions>` | Comma-separated extensions. |

**Default:** `(not set)`
Accepts `.xml`, `.config`, `.nuspec`, `.resx`, `.runsettings`, `.ruleset`, `.xsd`, `.xsl`, `.xslt`, `.manifest`, `.vsixmanifest`, `.xaml`, `.axaml`, `.wxs` and `.wxi`, with or without the dot. Files with these extensions are formatted as generic XML, so whitespace in element-only content may be re-indented.
*This option accepts a freeform value. No canned example is generated.*
