Case sensitivity in the Confluence macro name

Hey. Do you know if the macro names in Confluence are case sensitive? Not according to the documentation (Macro Module).

In our application, I defined an element in the application-plugin.xml file with the macro name ‘EasyMind’. In the VIEW mode of the Confluence page everything works fine, but in the EDIT mode the macro appears as Unknown macro: ‘easymind’ (lower case). See attachments.

When I change the name of the macro in the application-plugin.xml file to ‘easymind’ (lower case), everything works fine in VIEW and EDIT mode.

And that brings me to the fact that the name of the macro must be written in lower case. Is my assumption correct? Does anyone have similar experience with this?
