I have a question about relation between displaystyle attribute
of mstyle and display attribute of math element.

There is a disctiption in as follows:
For an instance of MathML embedded in a textual data format 
(such as HTML) in "display" mode, i.e. in place of a paragraph, 
displaystyle = "true" and scriptlevel = "0" for the outermost 
expression of the embedded MathML; if the MathML is embedded 
in "inline" mode, i.e. in place of a character, displaystyle = "false" 
and scriptlevel = "0" for the outermost expression. 

See Chapter 7 The MathML Interface for further discussion of 
the distinction between "display" and "inline" embedding of 
MathML and how this can be specified in particular instances. 

There is also a discription about display in 7.1.2 as follows:
The display attribute replaces the deprecated mode attribute. 
It specifies whether the enclosed MathML expression should be 
rendered in a display style or an in-line style. Allowed values 
are "block" and "inline" (default). 

Though there is no discription about relation between values 
of display and displaystyle, it seems to me that these
two paragraphs imply that display="block" should set 
displaystyle="true", and display="inline" should set 

Is this interpretation correct ?
