My browsing indicates yes and no. See for example 
http://docstore.mik.ua/orelly/xml/schema/ch07_05.htm
from which I quote "The location, the whitespace processing, and the 
datatype of these text nodes cannot be restricted in any way."
and further "when a content model is mixed, the position of the text 
nodes cannot be constrained, and this permits text nodes within the base 
type at any location."

HOWEVER, it does appear to be true that XSD allows you to constrain the 
order and frequency of *element nodes* within mixed content.

See e.g. http://www.w3schools.com/schema/schema_complex_mixed.asp

Also at 
http://www.informit.com/library/content.aspx?b=STY_XML_21days&seqNum=80 
I read:

"...whereas DTDs provide only partial support for mixed-content models, 
schemas provide a more complete syntax that allows you to specify the 
order and number of child elements in mixed-content elements. However, 
it is important to note that although you can declare mixed-content 
elements, you should avoid doing so if possible."
