Looking at the IDN implementation guidelines, item #5 states:

5.All code points in a single label will be taken from the same
  script as determined by the Unicode Standard Annex #24: Script
  Names <http://www.unicode.org/reports/tr24>. Exceptions to this
  guideline are permissible for languages with established 
  orthographies and conventions that require the commingled use of
  multiple scripts. Even in the case of this exception, visually 
  confusable characters from different scripts will not be allowed 
  to co-exist in a single set of permissible code points unless a 
  corresponding policy and character table is clearly defined.

So it would not be possible to have multiple languages associated to a label.

XML Schema "language" type[1]:

[Definition:]   language represents natural language identifiers as defined by by [RFC 3066][2] . The ·value space· of language is the set of all strings that are valid language identifiers as defined [RFC 3066] . The ·lexical space· of language is the set of all strings that conform to the pattern [a-zA-Z]{1,8}(-[a-zA-Z0-9]{1,8})* . The ·base type· of language is token.

3.3.3.1 Constraining facets

language has the following ·constraining facets·:

	• length
	• minLength
	• maxLength
	• pattern
	• enumeration
	• whiteSpace
