The ASN.1 module below is more general than the examples posted by
others. It is also more complete. When combined with an E-XER
encoder/decoder this module will handle XML like:

<text class='random'>Some default text <b>Bold<i>bold and italics</i>
Just Bold </b> No Bold <i id='X'>italics</i> No Italics </text>

I believe that this is what Simon was asking for. Does this do it?

-----------------------------------------
TextDemo DEFINITIONS XER INSTRUCTIONS AUTOMATIC TAGS ::=
BEGIN

Text ::= [NAME AS UNCAPITALIZED] Foo

Foo ::= [NAME AS UNCAPITALIZED] [ELEMENT] [EMBED-VALUES] SEQUENCE {
  embed-values SEQUENCE OF UTF8String,
  tags [ANY-ATTRIBUTES] AttrList (CONSTRAINED BY {}),
  choice-list [UNTAGGED] SEQUENCE OF [UNTAGGED] CHOICE {
	b   Foo,
	i   Foo,
	u   Foo
    }
} (CONSTRAINED BY {})

AttrList ::= SEQUENCE OF UTF8String

ENCODING-CONTROL XER
    GLOBAL-DEFAULTS MODIFIED-ENCODINGS
END
-------------------------------------------

Since this issue seems fairly sensitive, I'd appreciate guidance on
cleaning this little example up from any of the ASN.1 guru types that
may be reading this...
