setting up a rule involving 2 or more elements within an XSD file

[varocho]

Is there a way to set up a rule involving 2 or more elements within an XSD file? Some examples of the kinds of rules I mean:

'element2' is required is 'element1' has a value of 1

The value of 'element2' is in the range 100-200 if the value of 'element1' is 'A', 'B' or 'C'.

I think the only way to do this is use a choice and put all the possible arrangements into it.

Something along the lines of:

choice
<element1>1</element1>
<element2/>
or
<element1>not 1</element1>

How would I set up validations for the following?

<fld fld_id='1'>
<fld_val>100</fld_val>
</fld>
<fld fld_id='2'>
<fld_val>Yes</fld_val>
</fld>

where 'fld_val' has to be between 50 and 150 when 'fld_id'='1' and 'fld_val' has to be either 'Yes' or 'No' when 'fld_id'='2'.

Schemas are not my strong point. I'm not sure this is possible. You may need to use a schematron:
