Ashok Yes'Ive created the <xsd:pattern value="((2[0-9][0-9][0-9])|(1[0-9][0-9][0-9]))((0[0-9])|(1[0-2]))(([0-2][1-9 ])|(3[0-1]))"/> but to check all 31-30 month or febuary thats more complicated thats why i would like to use standard xsd:dated format and use it with CCYYMMDD format instead of CCYY-MM-DD.

To write the schema, you would first create a simple type that restricts "string" with a pattern corresponding to the format discussed above. This pattern should, as far as possible only allow legal date values i.e. the first D in the DD field should allow only 0,1,2 or 3. The bigger problem is whether you want to disallow February 30 and November 31 with a pattern.

If you need to markup some actual text in another format, or you otherwise want to keep another format, I suggest you use something like <date value='CCYY-MM-DD'>CCYYMMDD</date> Regards, Martin. P.S.: If somebody can write a schema for the above fragment, we'll probably add it (in one form or another) to the type library.
