positive.code: |`collectionsHandler` |As above, for custom CollectionsHandler implementations.
  | `infoHandler` |As above, for custom InfoHandler implementations.
  |`coreLoadThreads` |Specifies the number of threads that will be assigned to load cores in parallel.
  |`coreRootDirectory` |The root of the core discovery tree, defaults to SOLR_HOME.
  |`managementPath` |Currently non-operational.
  |`sharedLib` |Specifies the path to a common library directory that will be shared across all cores. Any JAR files in this directory will be added to the search path for Solr plugins. This path is relative to the top-level container's Solr Home. Custom handlers may be placed in this directory
  |`shareSchema` |This attribute, when set to true, ensures that the multiple cores pointing to the same Schema resource file will be referring to the same IndexSchema Object. Sharing the IndexSchema Object makes loading the core faster. If you use this feature, make sure that no core-specific property is used in your Schema file.
  |`transientCacheSize` |Defines how many cores with transient=true that can be loaded before swapping the least recently used core for a new core.
  |`configSetBaseDir` |The directory under which configsets for solr cores can be found. Defaults to SOLR_HOME/configsets

  ==== The `<solrcloud>` element
  
  This element defines several parameters that relate so SolrCloud. This section is ignored unless the solr instance is started with either `-DzkRun` or `-DzkHost`

  == Defining solr.xml
  
  You can find `solr.xml` in your `$SOLR_HOME` directory (usually `server/solr`) in standalone mode or in Zookeeper when using SolrCloud. The default `solr.xml` file looks like this:
