XML attribute vs XML element
...r example, attribute set choices. For example use (startDate and endDate) xor (startTS and endTS) is not possible with the current schema language
If XML Schema starts allowing the "all" content model to be restricted or extended then I would probably drop it

@gili: you can always just xor the dwords together to get a single resulting dword.

hash function for string
...ay to do that is to rotate the current result by some number of bits, then XOR the current hash code with the current byte. Repeat until you reach the end of the string. Note that you generally do not want the rotation to be an even multiple of the byte size either.
For example, assuming the common...

...t, like MD5 (128 bits) or SHA1 (160). Then you can shorten that further by XORing sections of the digest with other sections. This will increase the chance of collisions, but not as bad as simply truncating the digest.
Also, you could include the length of the original data as part of the result to...

三、“异或”运算符(^)
也称XOR运算符。
1、运算规则
若参加运算的两个二进位同号，则结果为0（假）；异号则为1（真），即：
0^0=0，0^1=1，1^0=1，1^1=0.
