If I can remember correctly, I implemented the regular 
expression validation of Dates(like Feb28 etc) in the schemas(around 3 years 
back). There are bunch of code examples across the web for this. So, we can do 
validate the dates or for a given set of values- enumerated data (like days of a 
week) etc in the Regular expressions. 
 
The date format decides the validation regular expression 
expression(ex: Regular expression for dd-MMM-yyyy is diff from 
mm/dd/yyyy)
 
Thanks,
Sreeni

Regular expressions may work to some degree in this case, but they won't 
provide the level of validation for units that you need. For example, a regular 
expression can be used to define the format for a date, but it cannot validate 
that a date of (for example) February 30 is not present, as it cannot validate 
the combination of month and year in this case. 
 
So Len's example of an attribute for units, with an enumerated list of 
valid values, is the best approach.

Hi Mangesh,
You can have this in Schema.
Define simple type attribute and have a regular expression 
as the constraint on that simple type attribute according to your data+units 
combination.

Hi All,<o:p></o:p>
<o:p> </o:p>
I am creating a xml schema where I 
have to making a ‘attribute’ but can a attribute hold a value and 
unit.<o:p></o:p>
My example is FlowRate, let’s the 
value and unit could be 100 GPM.<o:p></o:p>
Can I have just one attribute for 
100 and GPM both. Some times it might be 80 cFPS.<o:p></o:p>
<o:p> </o:p>
So can a attribute hold both or do I 
need element here.<o:p></o:p>
<o:p> </o:p>
Thanks,<o:p></o:p>
