but expln without anything give no value.

Basically, those are special "constants" that xcas uses when passing around certain arguments - usually categorical type things. For example, colors, specific type of a function and similar. I'm not certain what possible benefit allowing them to automatically convert into numerical values has versus an error when encountered in an incorrect useage, but that is the default behavior of the xcas software.
